Inspection Trends / October 20126
Dear Readers,
During this election season, Im sure
that, like me, youve been bombarded with
telephone calls asking you to vote for a
particular politician, donate to a
candidates campaign, or answer questions
for any number of polls. And, again, if
youre like me, youre ready for the
elections to be over, just so you dont have
to deal with the calls anymore. Calls that,
of course, always seem to come during the dinner hour.
Now all the calls I receive are either recorded messages or those
computer-generated robo calls, and I mostly ignore them. But if I
knew for certain that I could actually speak to a candidate, I might just
have something to say to that person. Because I have a pet peeve with
most politicians at all levels and both parties with regard to
education in this country.
How many times have you heard a politician and Im talking
about at the state as well as national level emote that Every child in
America needs to go to college! And while they dont specifically refer
to a university, we all know thats what they mean. That drives me crazy.
I believe every child should have the financial means to go to college,
but no, not every child in America needs to go to college. What every
child needs is training beyond high school. That training may mean a
four-year university, but it could also come from a community college,
vocational/technical school, or some other sort of specialized training.
In addition, I believe the politicians rhetoric gives our young
people unrealistic expectations. Now Im not saying that people cant
rise above their beginnings. I firmly believe in the American dream that
anyone can be whatever they want to be through education and hard
work. Im saying it makes kids feel there is something wrong with them
if they dont want to go to college; that it makes them ashamed to say, I
want to be a carpenter, electrician, cook, landscaper, welder, weld
inspector (you fill in the blank). And it makes parents not want to
encourage their children to become a part of any of those professions.
So what does this have to do with this issue of Inspection Trends?Well, education is the primary topic for this issue. Youll see profiles of
three educational institutions two community colleges and an
accredited vocational school that offer programs in nondestructive
examination. Theyre getting students who are transitioning right out of
high school, displaced workers retraining for new careers, and people
who want to upgrade their skills. The community colleges offer
associate degrees, of course, but all three programs are geared to getting
students into the work force.
I know that in the world of welding, were getting reports of
increased enrollment and new welding education programs opening up.
The schools profiled here have experienced growth in their NDE
programs as well. I hope those are all signs that recognition is coming
that we need workers of all kinds and that theres all sorts of great
careers out there, not just ones that require a four-year degree.
If you have any comments, please contact me at
[email protected] or (800) 443-9353, ext. 238.

Liberty Second Stage Closer to Production
Astrium, the Europeanaerospace company, recentlycompleted a set of tests on tankstructures to prove that keydesign and manufacturingprocesses used for Arianelaunchers are ready forproduction of the Libertycommercial launch vehiclesecond stage with ATK.
Liberty is a completecommercial crew transportationservice, including thespacecraft, abort system,launch vehicle, and bothground and mission operations.The planned first test flight isset for 2014 and a Libertycrewed flight in 2015.
Astrium, as a majorsubcontractor, will provide thesecond stage of the Libertylaunch vehicle, based on the
liquid-fueled cryogenic core of the Ariane 5 vehicle poweredby the Safran-built Vulcan 2 engine. Work done to completethe stage testing includes the machining, forming,computerized automatic welding and inspection of cryogenictank elements to provide the increased thickness andstiffened profiles necessary for the Liberty second stage.Another tank panel of increased thickness was welded andtesting in a cryogenic environment at the Euro Cryospacefacilities, an Astrium and Air Liquide joint venture.
These tests take the Liberty second stage one stepcloser to production, said Alain Charmeau, CEO of AstriumSpace Transportation. They demonstrate conclusively thatour proven processes can manufacture thicker and stiffercryogenic tanks for the Liberty second stage. Welding,machining, and forming space hardware is a highlysophisticated industrial process.
LTI Adds Fracture Toughness Testing Services
Laboratory Testing, Inc. (LTI), Hatfield, Pa., recentlyadded fracture toughness testing to ASTM Standards E399and E1820 to the list of services it provides.

between 150 and 350F. The company has fixturing to test
specimens in a range of sizes, including single edge bend and
compact tension specimens. Fracture toughness tests require
precisely machined specimens prepared to specification.
LTIs machine shop prepares all required specimens,
including those with an EDM notch. Additional information
is available at www.labtesting.com.
SGS Completes Tank Inspections in Liberia
SGS SA Industrial Services recently completed the
out-of-service inspection of two idle tanks in Liberia in order
to determine whether they could be successfully and safely
returned to operation and to provide a relevant repair
program. The work was done for Second Harbor Engineering
Co., Ltd., a wholly owned subsidiary of China
Communications Construction Co., Ltd.
The tanks had been idle for years. SGSs inspectors
follow the requirements of API 653, Tank Inspection, Repair,Alteration, and Reconstruction. Due to the complexity of theLiberian project, SGS assigned two experienced inspectors to
examine the two tanks, which had volumes of 3100 and
26,000 m3, respectively. The inspectors performed vacuum
box testing, visual inspection, magnetic particle testing,
plumbness and settlement surveys, ultrasonic thickness
testing, and other methods. After completing the inspection
phase, the company designed a repair protocol based on the
current status of the tanks and in compliance with the API
653 requirements.
In other news, SGS recently entered into an alliance with
Atlas Material Testing Technology, a provider of accelerated
weathering instruments and weathering testing services. The
alliance allows for the expansion of the Atlas 25+
photovoltaic module durability test program.
Carestream Hires Regional Sales Manager

Safety Tip Offered
With regard to the article Performing Inspections inConfined Spaces in the July 2012 issue, as an independentinspector, I never know where or for whom I will beinspecting. Even though I have never had a work-relatedinjury, there have been injuries to others. When on the jobsite, they know nothing about me or my personal or medicalhistory. Through my sports background (cycling and inlineskate racing), I obtained a personalized ID bracelet fromwww.roadid.com. It can contain up to six lines ofinformation. Mine has name, address, emergency phonenumber, medical insurance provider, blood type, and NKA(no known allergies). I have no affiliation, monetary orotherwise, with Road ID.

Reader Comments on Safety Issues
I always enjoy reading the Welding Journal and InspectionTrends. As a former instructor at Oak Ridge High School andthe Tennessee Technology Center in Knoxville, Tenn., I wasalways using information from both magazines to share withmy students. One subject that was stressed first, and as mostimportant, was safety. Pictures were always a good learningtool, especially for the high school students. But there would betimes a picture would show a safety violation(s). The picture(s)would be representing a different subject and not necessarilysafety. It just surprises me that these unsafe practices were notcaught while the picture(s) was being taken and before beingpublished. Some examples are in the July 2012 issue ofInspection Trends.
On page 18, the welder in the picture is not wearing safetyglasses while using a slag hammer. On page 19, the welder inthe photo at left has his jacket unbuttoned, exposing his T-shirtto a possible burn or fire. The picture to the right has a welderusing a sledgehammer to test his weld with his welding helmetstill on. The extra weight not needed at that time couldpotentially cause a neck injury.
I dont want you to think I am picking on AWS, becauseIm not. Its just that I am proud to be a welder, a CWI, amember of AWS, and a contributor from time to time. I wantAWS to stay the example for others to follow. Safety first.

Readers Weigh in Regarding QualifyingWelders on Fillet Welds
After reading the discussions by both Mr. Fluckiger(Understanding Welder Performance Qualification, page 11,July 2012) and Mr. Moore (Qualifying Welders on Fillet Welds,page 17 of the same issue) combined with my 21 years in theindustry, I agree with Mr. Fluckiger that the present way in
which welders who are qualified in groove welds are alsoqualified in fillet welds is correct. All the welders who werequalified in groove welds that I attended to made good filletwelds. We never had the problems Mr. Moore described. Hisidea would just complicate the industry even more for noreason that will merit this type of change. With all due respect, Igive Mr. Moores suggestion two thumbs down.
Joseph De PasqualeSCWI, Los Angeles, Calif.
I have been in the structural steel business for 34 years as awelder, supervisor, plant manager, and CWI/CWE, and I wouldlike to comment on Mr. Moores article about welderqualification.
AWS D1.1 has been written, revised, and rewrittennumerous times regarding finding and using the most commonprequalified joints most job shops would use. What he proposedunder the A Modified Test heading would not meet theprequalified status of AWS D1.1 in the as fit up tolerances asshown in Fig. 3.4, Prequalified Joints, and would be beyond thegiven tolerance in AWS D1.1.
The cases in which a welder may or may not need to betested should be in the contract documents and what code thatparticular job may be under should also be listed. If not, animmediate request for information (RFI) should be sent out. Onreturn of the RFI, if a code has been referenced, a PQR andWPS should be written along with job-specific welderqualification.
If a code is not referenced, we as CWIs cannot dictate whatkind of test would need to be administered. Our job is to followthe given code that is being referenced to the best of our abilityand not make up our own rules. Only the Engineer of Recordhas the right to make changes to a particular code along withany special testing that may be needed including welderqualification.
I believe when welders fail the fillet weld break test or anyother test, it is solely due to not having enough training andexperience along with poor technique.
Most job shops want welders to start production as soon asthey are hired, assuming they can pass a WPQR. Trainingwelders should be a priority of every fabricator and AWS.
Fillet and groove welder qualification tests are a primaryfunction test of the welder and should not be changed. If awelder cannot pass a fillet or groove test, then that welderneeds more training.
Jim St.AmandQC Manager, CWI/CWE, United Steel, East Hartford, Conn.
I am an AWS CWI and CWE. I had 26 years of weldingbefore taking the leap (into inspection). So I am a veteranwelder and budding inspector, if you will. The welding fieldhas been and continues to be as rewarding as it ischallenging.
This is my take on the proposed welder performance testfor combination fillet and groove welds.
There is a test that one of my customers requires that I
-
Inspection Trends / Fall 2012 11
qualify personnel by. It consists of a single-bevel groove weldfor GMAW joint designation B-U4a-GF, as shown in Fig. 3.4of AWS D1.1/D1.1M:2008. When used with a 38-in. rootopening on 38-in. material with backing, I feel it performs thesame function as the proposed test in the article with oneadded benefit. B-U4a-GF has an advantage over the other inthe aspect of backing strip removal. The one proposed in thearticle has a 1516-in. root opening and will make removal of thebacking strip more of a chore and hinder an accurate cut witha band saw. It will also take more time due to added materialto cut through. Removal of the backing strip will most likelyrequire use of a milling machine. For some, this will certainlylimit in-house coupon preparation for the guided bend test.
Mid-size to larger welding facilities that employ a dozenor more welders and an in-house CWI generally do in-houseperformance qualifications due to the cost of outsourcing.They send out for third-party testing for procedurequalification more for impartiality reasons.
While I can understand and agree with the frustration thatfillet weld break tests are more difficult to pass than groove

FeatureBy
Inspection Trends / Fall 2012 13
By Gary S. Martin
As the newly installed chairman ofthe inspection Clause (6), of AWSD1.1, Structural Welding Code Steel, I was honored with a request towrite an article for Inspection Trendsrelated to that clause in the code. Otherthan that, I was given a blank slate towrite about. Unfortunately, Im not ablank slate type of writer, so my friendJohn Gayler, a former D1 secretary (acritical job in keeping the committeeon track) gave me some ideas to writeabout. As a former D1 Committeesecretary, he saw all the inquiries thatcame in about all the D1 codes, and hewas able to offer plenty of ideas for meto write about. Following are answersto some often-asked questions. Keep inmind that any opinions expressed aremine alone.
Regarding Section 6.1.4.1 on whetherCWIs are required, how is option #3determined?
When determining therequirements for a fabrication projector product that falls under the scope ofAWS D1.1 Structural Welding Code Steel, you must review the contractdocuments. The requirements listed inthe code are only mandated wheninvoked by the contract. The Engineer,per Section 1.4 of the code, isresponsible for developing the contractdocuments. The code also allows widelatitude to the Engineer on makingmodifications or exemptions to thecode language. In the area of inspectorqualifications, there are three optionsoffered to the Engineer forconsideration in the contractdocuments. They are as follows:
1. Current or previous certificationas an AWS Certified Welding Inspector(CWI) in conformance with theprovisions of AWS QC1, Standard forAWS Certification of WeldingInspectors. Note that the inspector isnot required to have an active CWI
certification, only a prior one. It can bestipulated in the contract as to whetheror not a current certificate holder isrequired.
2. Current or previousqualification by the Canadian WeldingBureau (CWB) in conformance withthe requirements of the CanadianStandard Association (CSA) StandardW178.2, Certification of WeldingInspectors. This is offered as areciprocal agreement with CSA/CWBas their code and inspector certificationprocesses are very similar to those ofthe American Welding Society.
3. An individual who, by trainingor experience, or both, in metalsfabrication, inspection, and testing iscompetent to perform inspection of thework.
So Option 3 flies in the face of thetypical paradigm of requiring formallytrained and certified personnel toperform inspections, especially finalproduct release inspections, as is thecase. To get more insight on thisoption, the first thing I would do is goto the code commentary that coversthat portion of the code.
For those who have never lookedat the commentary of the code, it canbe a useful place to find furtherexplanation, examples, and guidanceon what the code language is trying toconvey. As formally stated in theforeword of the commentary, Thiscommentary on AWSD1.1/D1.1M:2010 has been prepared togenerate better understanding in theapplication of the code to welding insteel construction. The commentary islisted in the back of the code asinformation only, since this kind ofwording cannot be placed in the codelanguage itself. I like the fact that thereis this section in the code, and I wishother industry codes followed suit.
All that being said, there is,unfortunately, no commentarylanguage covering Section 6.1.4.1. It
actually skips from C-6.1.3 to C-6.1.5.Just my luck. That would havecertainly made this section easier towrite.
So I have to be careful here, else Imight be perceived as a one-mancommittee, writing code commentary.Even though it is not mandatory codelanguage, commentary language is stillproposed, discussed, and voted onbefore being added to the code.
So Im just going to offer myopinion as to why this third optionwas added. I dont have the completerevision history of the D1.1 Code, asit goes further back than anyone whois still alive today. I cant conveywhen and how this language was putinto the code as I have only been onthe committee for seven years, and theearliest revision of the code I have is2002. I can tell you that somewherebetween the 2002 edition and thecurrent one, the only change made toOption 3 was that it used to say anEngineer or technician whereas nowit only states an individual, furtheropening up the potential resourcepool. I can only hazard a guess thatthe reason for this third option is thatthere still arent enough CWIs in theworld to staff all the code-coveredprojects and there needed to be somerelief to this to allow projects to goon. It doesnt mean that just anyperson off the street will be approvedto conduct code inspections. If theEngineer approved this option in thecontract documents, he or she willalso likely have some stipulation onwho can be hired for this work. Mostlikely a rsum review, personalinterview, and some sort of practicaltest or examination will be conducted.In fact, Section 6.1.4.5 states thefollowing: Verification Authority. TheEngineer shall have authority to verifythe qualification of Inspectors.

that I have known never bothered to
become certified. Even those who have
taken the test and failed can still be
excellent inspectors; it just may mean
they are not good test takers. Again, as
the Engineer carries great
responsibility in forming the contract
documents, it behooves him or her to
be careful in selecting the options for
inspector qualification for the project.
Who decides? Can an individuals
qualification be challenged? How
and by whom?
Well, we have already established
that there is no code commentary on
this code language, so no help there. I
guess as chairman of that clause task
group, I should propose some code
commentary: Ill put that on my to-do
list. Anyway, back to the subject at
hand, who can challenge an Option 3
inspector qualification? Well, for one,
the seller or contractor bidding on the
project can challenge anything in the
contract before it is accepted. Thus,
the seller may insist on using in-house
trained inspectors rather than having a
currently certified CWI or SCWI
manage all inspections. Of course, if
the buyer or customer insists on
current CWI certificate holders, the
seller may adjust its price and cycle
for this, and the customer can then
decide if it is worth the money and
time or not. There is always a balance
in any buyer-seller situation.
Typically, you dont get something for
nothing, and you usually get what you
pay for. There is also a term called
Authority Having Jurisdiction (AHJ).
Countries, states, provinces, counties,
cities, municipalities, and even home
owners associations can make some
or all of the code language mandatory
and can make modifications or
exemptions to the code language.
They can mandate certain options in
this regard or add controls on top of
Option 3. Another source to answer
this question is to look at the code
language covering CWIs in AWS
QC1. This is one of the free
publications that AWS offers, so
anyone can download it
(www.aws.org/certification) and seewhat it says about certification of
welding inspectors.
To answer this question, I looked
over QC1 again, something I hadnt
done since my last nine-year
recertification as a CWI, and I found
something interesting in Section 11
Code of Ethics, Rules of Conduct, and
Practice. Section 11.3.2 states as
follows: The SCWI, CWI, or CAWI
shall publicly express no opinion on
welding inspection subjects unless it
is founded upon knowledge of the
facts in issue, upon a background of
technical competence pertinent to the
subject, and upon honest conviction of
the accuracy and propriety of the
statement.
That being said, here I am
publicly expressing an opinion on
welding inspection subjects. Well, I
think I am safe here as Im sure I have
sufficient background, credentials,
training, and experience on the issue
to write about it.
So all that aside, what does QC1
say about challenging a CWIs
qualifications and how does that relate
to Option 3? Well, that sort of flies in
the face of a central certification
system such as the AWS CWI
program, as one of the key premises
of the program is that one need not
challenge a CWIs qualifications, as
that has already been vetted by the
AWS via a stringent examination and
certification process. Anyone who has
tried to obtain CWI certification
knows that you have to have a certain
amount of fabrication/inspection
experience, pass written exams, and
have good or correctable vision. You
must also maintain and document your
inspection experience and acceptable
vision every three years, and
document continuing education credits
every nine years to maintain your
certification. So, you really cant
challenge the qualification of a current
CWI certificate holder, you can only
challenge the conduct of the person
who may be in noncompliance with
the CWI Code of Ethics, Rules of
Conduct, and Practice. In other words,
we have to leave it that the buyer can
challenge the Option 3 inspector
qualification via contract
development, but not Options 1 or 2
inspector qualifications, except
perhaps that the CWI be a current
rather than past certificate holder.
Flaw, Discontinuity, Indication,
Defect, and Non-Conformance:
Are They the Same?
Recently, I was teaching a class
on NDE to some company personnel
using material someone else had
prepared that said nothing about these
terms. Its a pet peeve of mine that
many people, including NDE
professionals, bandy these terms about
incorrectly, which further increases
the misconceptions about them. There
are two places in AWS documentation
to find the meanings of these terms.
First is AWS A3.0, Standard WeldingTerms and Definitions. The second isthe definitions section of the specific
code, which may have additional or
specific definitions for terms used
exclusively in that code. The AWS
D1.1 Code and other D1 codes often
have definitions that differ from the
AWS A3.0 terms. In the 2010 D1.1
code, these are found in Annex K.
Lets see what these terms mean and
how the AWS codes define them.
Defect
D1.1: A discontinuity or
discontinuities that by nature or
accumulated effect (for example, total
crack length) render a part or product
unable to meet minimum applicable
acceptance standards or specifications.
This term designates rejectability.
A3.0: A discontinuity or
discontinuities that by nature or
accumulated effect render a part or
product unable to meet minimum
applicable acceptance standards or
specifications. The term designates
rejectability. See also discontinuity and
flaw.
The definitions are nearly the same,
except D1.1 gives an example of
accumulated defects and doesnt
reference discontinuity and flaw. I think
that reference can be confusing because
those are not the same as defect.
Discontinuity
D1.1: An interruption of the
typical structure of a material, such as a
lack of homogeneity in its mechanical
or metallurgical or physical
characteristics. A discontinuity is not
necessarily a defect.
A3.0: An interruption of the
typical structure of a material, such as
a lack of homogeneity in its
mechanical, metallurgical, or physical
characteristics. A discontinuity is not
necessarily a defect. See also defect
and flaw.
Again, nearly the same, except
D1.1 doesnt direct you to defect or
flaw, though Im happy for the
-
Inspection Trends / Fall 2012 15
statement that a discontinuity is notnecessarily a defect.
Flaw
D1.1: Not defined.A3.0: An undesirable
discontinuity. See also defect.Okay, I have a bone to pick with
this definition. What constitutesundesirable, and what are we supposedto do about something undesirable? Isit rejectable? I dont think so. I alwaysthought flaw and discontinuity werethe same thing. Because I wanted tokeep an open mind about this, I lookedup both terms in an Oxford Dictionaryand, indeed, it describes a flaw assomething that is undesirable.However, I did find an interesting twistin one part of the definition: A fault orweakness in a persons character: Hehad his flaws, but he was still a greatteacher. To me, this says somethingcan have flaws, but still perform asintended. But, really, are anydiscontinuities desirable?
Indication
D1.1 defined for UT: The signaldisplayed on the oscilloscopesignifying the presence of a soundwave reflector in the part being tested. Generally, any response from a giveninspection method is an indication.
Non-Conformance
D1.1: Not defined.A3.0: Not defined.This term is used more in the ISO
code world, but carries the samemeaning as a defect. ISO chose thenon-conformance term to align withthe ISO 9000 series Quality Systemcodes, because it is a term used todefine a process that is noncompliant toan ISO requirement, and the termdefect didnt quite fit the vernacular ofthe ISO auditing world. However, itdoes nicely replace the term defect inall other code uses. We can say a defectis a nonconformance to the acceptancecriteria of the code.
To put it all in one sentence thatcan be remembered more easily: Anindication from an inspection processis a discontinuity or flaw that must beevaluated against acceptance criteriato determine if it is a defect ornoncompliance and subsequentlyrejectable to the code.
Explain the split between QA andQC regarding inspectionresponsibility. QC (inspector)required by code; QA (verification)not required, but a contract option.
Okay, lets look at the definitionsfor QA and QC in AWS A3.0oops,they arent defined there. Okay, letstry inspector; no, not there either.Verification? No, not there as well.Remember, A3.0 covers standardwelding terms and definitions. It reallyisnt supposed to cover NDT or otherinspection terms.
Lets see if D1.1 defines any ofthese terms. QC? QA? No. Inspector?No. Verification? No. John really gaveme a tough assignment here.Fortunately, Clause 6 in D1.1 doesdefine contractors inspection (QC) andverification inspection (QA).
Generally speaking, QC inspectionis performed by the producer orcontractor: 6.1.2.1 ContractorsInspection. This type of inspection andtest shall be performed as necessaryprior to assembly, during assembly,during welding, and after welding toensure that materials and workmanshipmeet the requirements of the contractdocuments. Fabrication/erectioninspection and testing shall be theresponsibilities of the Contractor unlessotherwise provided in the contractdocuments.
On the other hand, QA inspection(verification) is performed by theCustomer or Owner: 6.1.2.2:Verification Inspection. This type ofinspection and testing shall beperformed and their results reported tothe Owner and Contractor in a timelymanner to avoid delays in the work.Verification inspection and testing arethe prerogatives of the Owner who mayperform this function or, whenprovided in the contract, waiveindependent verification, or stipulatethat both inspection and verificationshall be performed by the Contractor.
Note the stipulation that the Ownercan waive this or reassign it to thecontractor.
Well, it seems that one wasnt sotough after all.
Which is correct, NDT, NDE, orNDI?
While which one of these terms touse is not really a pet peeve of mine, itdoes bring up the ire of many on the
code committee. I dont know if thishas been written about before inInspection Trends, but if it has, theanswer bears repeating in my opinion.NDT = Nondestructive testing.NDE = Nondestructive examination orevaluation.NDI = Nondestructive inspection.
Note that they all havenondestructive in common, but whichone is correct?
The wording in A3.0 is as follows:Nondestructive evaluation. A
nonstandard term when used fornondestructive examination.
Nondestructive examination(NDE). The act of determining thesuitability of a material or a componentfor its intended purpose usingtechniques not affecting itsserviceability.
Nondestructive inspection. Anonstandard term when used fornondestructive examination.
Nondestructive testing. Anonstandard term when used fornondestructive examination.
As you can see, AWS A3.0 statesnondestructive examination is the onlycorrect term and is the only one forwhich it lists the abbreviation, NDE.
Im not really sure why evaluationis not the standard. After all, isnt thatwhat a Level II does with the resultsfrom the nondestructive process?However, if you look at AWS D1.1Annex K, it states: *NDT.Nondestructive testing.
As stated previously, a code candefine nonstandard terms as long asthey are confined to that code. Thatswhat the asterisk means.
Here is the explanatory paragraphat the start of Annex K. The terms anddefinitions in this glossary are dividedinto three categories: (1) generalwelding terms compiled by the AWSCommittee on Definitions andSymbols; (2) terms, defined by theAWS Structural Welding Committee,which apply only to UT, designated by(UT) following the term; and (3) otherterms, preceded by asterisks, which aredefined as they relate to this code.
Now, that definition is pretty weakand there is a revision going throughcommittee to strengthen it, but until itmakes it into the code, I cant discussspecifics.
I have heard committee membersjokingly say that they will agree tochange NDT in AWS D1.1 to NDEwhen ASNT (American Society for
-
Inspection Trends / October 201216
Nondestructive Testing) becomes ASNE.By the way, why is it NDT/E/I
instead of NT/E/I, when nondestructiveis one word? My guess is our technicalpreference for TLAs (three-letterabbreviations).
But, on a serious side, A3.0 mayhave a point. Testing can be inferred tomean obtaining quantifiable resultsfrom a material or object. How strong,tough, hard, etc., is that material orobject? That information is usuallyobtained by destructive testing such astensile, bend, fracture, or hardness(although more and more you can dothis nondestructively) and with thenondestructive methods used today,there is no testing, only examination.
As for Inspection (NDI), it can beunderstood that inspection is a processto determine if a material or componentmeets requirements, without having toput any energy into the part as is donewith traditional nondestructivemethods, such as sound, radiation,
magnetism, or capillary motion (dyepenetrant). Inspection traditionallymeans just looking at an object ormaterial to determine if it meetsrequirements.
That being said, the most popularabbreviations for the six most usednondestructive methods all end in T.VT, PT, MT, UT, RT, and ET. Somaybe ASNT should change its nameto ASNE and the two-letterabbreviations should become VI (sinceno energy is imparted to the object invisual), PE, ME, UE, RE, and EE.
I personally believe usage justreally depends on whatever vernacularyou grew up with in the industry. Mostof the old codgers like me willcontinue to use NDT and the newgeneration will likely use NDE, andwhen enough of them are on thecommittee, NDE might become theofficial term in AWS D1.1. For now,we just need to agree they all mean thesame thing.

FeatureBy Rand Ernst
Central Piedmont CommunityCollege (CPCC) is an accredited, two-year community college located inCharlotte, N.C. Approximately 70,000students are enrolled in the collegessix campuses, and there is also anextensive online component.
The Harper Campus in southCharlotte is home to CPCCsNondestructive Evaluation TechnologyProgram (NDET). The program is thebrainchild of Dr. Anver Classens who, asa welding engineer and division directorat the college, saw the need for trainedNDE personnel in the area, but there wasa lack of training facilities. His visioncame to fruition in the fall of 2007 withestablishment of the NDET program atCPCC. From a humble beginning of fourstudents, the program has grown in fiveyears to the current enrollment ofapproximately 90 students. The schoolhas recently completed a new 7000-sq-ftlab facility in which it has investedalmost $2 million dollars inequipment and supplies to build afirst-class educational environment.
The new facility includes anX-ray vault to house a new 320-kVportable X-ray machine anddarkroom (Fig. 1A, B), as well asclassroom and lab areas.
What the NDET ProgramOffers and EntranceRequirements
Central Piedmont CommunityColleges NDET program is one of thefew in the country to offer an Associatein Applied Sciences degree (AAS) innondestructive examination. The two-year degree is comprised of the coreinspection methods, welding, andblueprint reading classes, as well asgeneral education requirements in
English, mathematics, and socialsciences.
The NDE programs length andcontent follow the guidelines of theAmerican Society for NondestructiveTesting (ASNT), a professional societythat establishes recommendedguidelines for training and certificationof personnel in NDE in the UnitedStates. In order to be certified by anemployer, the guidelines require a
minimum number of formal traininghours as well as on-the-job experiencehours for each test method. Through acombination of lecture and hands-onlab work, CPCCs program providesthese required hours of training. Sincethese guidelines are the basis of theprogram, the colleges graduates satisfythe training requirements across thecountry and in most all industries.

In addition to the degree, thecollege offers a certificate program.Students earn certificates for specificNDE methods as they complete them,and it has been documented that thestudent has satisfactorily completed therequired training in that test method.Students can choose to go for thecertificate(s) alone or work toward adegree to get the certificates as they gothrough the program. The certificateallows the student to obtainemployment in a test method if anopportunity arises while continuing hisor her education or, if the need arises,to work before completing the fulldegree.
Another option available tostudents is a diploma in Nuclear PlantInspection. This is a course thatspecializes in advanced ultrasonicinspection of piping in nuclear powerplants, which is a highly technical andsought-after job skill.
Test Methods Covered
The test methods taught at CPCCare those considered the mainnondestructive examination methodsused in industry. While there are othermethods used in the various industries,CPCC teaches the most commonlyused and the core of the NDE business.The program includes classes in thefollowing methods:

Where Do CPCC StudentsCome From?
Contrary to the general conventionfor a community college, the vastmajority of students in NDET arentstraight out of high school. There is aneclectic mix of young people, not-as-young people with a lot of lifeexperiences, and people who have beenin the workplace for a few years andwant to train to do something else.Because of the economic downturn, thecollege has experienced an influx ofdisplaced workers, some of whom haveworked for years in a particularindustry, but have come back to collegefor retraining.
Central Piedmont CommunityCollege has an excellent weldingprogram that is also an AWSAuthorized Test Facility. The NDETprogram has gained some studentswho have graduated from thewelding program or who havechanged programs after having beenidentified as good NDE candidatesby their welding advisors.
The students have chartered theNorth Carolina Student Section ofASNT, and the group is very active Fig. 4. It is a means for students tonetwork with professionals in thebusiness who are the areas owners,managers, supervisors, and technicians.By working closely with the CharlotteASNT Section, students get to visitactual worksites and see the day-to-daywork environment. In addition, eachyear the students put on a benefit golftournament using the proceeds to sendstudents to the national ASNT FallConference where they network withNDE professionals from around thecountry, see the latest technology, andcan view various aspects of the industrythey dont get to see locally.

The Students Perspective
Justin Sadek is in his third semester and has already been working in NDE fora year and a half.
Since youve already been working in the field, has it beenworthwhile for you to come back to college?
The training that Ive received while attending Central Piedmont hashelped a tremendous amount. Being able to apply the theory with the hands-onapplications has made a world of difference. Being able to understand whatIm doing and why has helped me understand why Im getting the results Iam. Anyone can calibrate a machine or follow a procedure, but to understandwhat can and will change, plus understanding the theory behind it all helpswhen someone asks what Im doing and how it works.
Would you recommend the program to anyone else?I would recommend the NDE program because there is always an effort
to expand the program and provide as much knowledge as possible.
Giovanni Gbemudu is in his second semester in the NDET program. Hisbackground is in the fields of architecture/construction.
How has the experience been for you in the NDET program?The experience has been a confidence booster. Coming from a different
background, making the choice of NDT without full comprehension of theindustry left me anxious about the training requirements. Surprisingly, I amamazed at the similarities between NDT and architecture/construction and itsdirect influences on everyday life safety.
What are your career objectives and/or priorities?As I better understand the NDT world, the opportunities within are
becoming clearer. My ultimate goal would be to gain enough experience at alllevels and hopefully contribute to the NDT industries of the third world. I believethe third world in the near future will come to rely more on NDT as we have inthe United States today.
Would you recommend the program?Yes, I would. I feel I am already an ambassador of the program, and it
only benefits me to have a strong alumni group.
Nate White is a former student now working for Structural IntegrityAssociates, Inc. He has been working in the field for a little over a year and isbased in Charlotte.
What was your background prior to coming to CPCC?Prior to coming to CPCC, my background was in the handyman/
construction industry.How has the experience been and what has been your favorite part?The experience has been wonderful. I have enjoyed all of my classes,
and the instructors are always willing to help. My favorite part has beenlearning from instructors who have been in the field.
What kind of industries and what type of projects have you worked on?I have worked in chemical plants, new construction sites, and in fossil
plants.With what youve seen in the field so far, do you feel that there is a
current need for trained technicians and will there be a need in the future?Yes. There is a huge need in the NDT industry for well-trained
technicians. The industry is getting more and more advanced, and as theindustry continues to advance, we need well-trained people who can keep theNDT industry thriving!

With the college becoming betterknown in the industry, the hope is tobuild partnerships with companiesthroughout industry. Following are someof the ways this could be achieved: Having students work through the co-
op program. This is a win-winsituation for both the employer and thestudent because the student getsvaluable on-the-job training hours,sees how the work is actually done inthe field, and earns some money. Theemployer gets a trainee with a solidtheoretical background, who isanxious to learn the industry, andwhom the company can test out as a
potential future employee. Industry professionals could come and
speak at club meetings or directly toclasses. This would help studentsdispel their anxiety about not reallyunderstanding the day-to-day life of aninspector by hearing personal accountsof how the NDE business reallyworks. People who have specialexperience or equipment could sharetheir knowledge with the students.
Companies or manufacturers couldpartner with the school by loaning ordonating equipment. Industry wantspeople trained on the equipment thatthey use in the field and could beaccomplished through a loan ordonation program.

FeatureBy Joseph P. Kane
This is the final article in a four-partseries related to the Code of Ethicsfound in AWS QC-1: 2007, Standardfor AWS Certification of Welding
Inspectors.
Surely, most CWIs think they caneasily see a blatant ethical problemwhen they are confronted with one. Itis easy to see and avoid an outrightcash bribe. (Well, maybe the mind willget hazy, and the eyes will get foggy ifthe proposed bribe amount starts atnine figures to the left of the decimalpoint!) We know that we do not submitfalse welding inspection reports. Weknow we do not forge inspectionreports. We know that we do not signfor inspections that we do not perform,or for which we did not have directknowledge. We know that we do notpostdate reports or backdate reports ifthat action is meant to imply somequality that does not exist, or toconfuse the reader, lead the reader toinfer some quality that is incorrect, orsupport some dishonest venture.
However, I think the personalcomputer age brings new problems thatwould seem to be outside currentinterpretations of some of theindividual articles of the AWS Code ofEthics, Rules of Conduct, and Practice.I think it probable that the AmericanWelding Society will not be able towrite a comprehensive policy that willcover even a small part of the ethicalsituations that will be posed because ofthe use of computers and new reportingsystems. It is likely the requirements ofour customers to use computer systemswill require actions and reports that aregoing to pose some very differentethical challenges, and will createconundrums and ambiguities that donot fit the traditional idea and conceptof ethical conduct and practice.
Computer Reporting Systemsand Electronic Signatures
It is likely that most of us wouldnot sign for something on a report thatwe did not agree with, or sign forsomething we did not inspect orwitness. This seems to be a simpleconcept, but the computer age bringsout scenarios that can start any numberof what if situations. What is meantby personal knowledge throughdirect supervision (Article 11.2.5)? Iam concerned that computer reportingprograms, which are designed tostandardize project management,inspection recording, record keepingand reporting, may not leave enoughoptions to the inspector to fully complywith all the articles of the AWS Codeof Ethics, Rules of Conduct, andPractice as they exist today.
For example, right now I aminvolved as a third-party QA Inspectorfor a department of transportation(DOT) in a state that uses a computerprogram for all reporting activities. It isbasically a paperless system. However,in this filing system, some of theseparate reporting items are listed withme as the witness or as the inspector ofrecord. The reporting system includessign-off blocks for the dates of variousfabrication steps. I can only guess atsome of these dates, yet I have to fill inthe fields on the electronic form. Thesedates are really not critical to thequality or serviceability of the item, butit worries me when I have to enter adate that is simply my best guess.There is no remarks field where I canwrite in a disclaimer.
In some cases, I am required to fileother inspectors reports, and there isno way for me to refuse to accept thosereports. For instance, in the case of QCmagnetic particle testing (MT) report
submissions, I am automatically listedas witness. In many instances I may nothave witnessed all, or even any part, ofthat particular activity. Now, I havetaken advantage of an optional field inthis particular electronic report to posta short comment. I usually write I didnot witness any of this activity, Ionly observed part of this activity, or,I only witnessed MT on pieces 86F1and 86F2. There is also a field in thatsame report that has a drop-down menuthat asks, Report Accepted? 1. Yes, 2.No. The report doesnt give me anyother choices. So, I accept the report,because QC was required to submit anNDE report for me to enter, and I amrequired by contract language to enterit.
Sometimes I do not agree with theway the QC Tech does MT, so inaddition to the witnessing disclaimer,I also enter my technicaldisagreement remarks in the commentblock. To be safe and redundant, Iusually also make additional notes inmy separate Daily Narrative Reportdisclaiming 100% surveillance and/orexplaining my objections about thefabricators NDE activity.
Are all these disclaimersnecessary? I think so because I am stillthe person signing off on this activity.And, yes, it is often quite timeconsuming. Even if I do not actuallyphysically sign anything, I am stilldeemed to be the responsible inspectorfor the project. I am not a lawyer, so Ireally dont know how much can beused against me in a court of law, but Ijust wouldnt want to bet my career onit. Even if it is not a court of law, howdo you defend your activity or lack ofactivity to a DOT supervisor, or to anAWS Hearing Panel?

impossibility of adequately and
completely covering the whole project to

one of the state DOT engineers to whom
I report. He said the state recognizes it is
only paying for part-time or partial
coverage. The state emphasizes that you
are only a QA inspector, not a QC
inspector. Your primary job is to make
sure that the fabricators QC does all the
checks and tests for which they are
contractually obligated. In his words,
You only perform spot check
inspection. You are not expected to catch
everything, their QC is.The state policy is that it only
gives contracts to fabricators who havea nationally recognized fabricatorcertification such as from the AmericanInstitute of Steel Construction.Fabricators are required to have currentCWIs on the floor whenever there iswelding being performed, and theCWIs are to perform the inspectionfunctions. American Society forNondestructive Testing SNT-TC-1A-qualified technicians are required toperform NDE operations other thanvisual testing. A real, documented, andfully operational quality program hasto be in place, and it has to be actuallyused in daily operations. The statebelieves these prerequisites will weedout the hacks and fly-by-nights.Finally, the fabricator is required todemonstrate several years ofexperience, and pass a cursory audit bythe state or its designated inspectionagency. After all this, it is deemed thatonly QA spot checking of the operationwill ensure product quality. (Ha! If allthis inspires your confidence, maybe Ishould stop here and try to sell you abridge in Brooklyn, N.Y., for realcheap! But, that would be a fraudulent or dishonest venture anda clear violation of the AWS Code ofEthics, Rules of Conduct, and Practice,Article 11.2.6.)
I assume the Engineers I report toare honorable men. I truly believe themwhen they tell me what they expect ofme. I accept that they recognize that Iwill miss many things when I am doingonly partial inspection activity. Butwhat happens after they retire or arepromoted? What would happen, ifsometime in the future, there was afailure and another Engineer/Investigator researches the causes ofthe failure? Suppose he findssomething I missed, or something Iroutinely did not do, or my signature orjust my electronic name associatedwith some pertinent approval
document? This failure may havehappened shortly after the bridge is inoperation or several years from now. Inthat case, I dont know if I would evenremember anything about the failedpart. Without that disclaimer, andwithout the support of the Engineer, Icould be thrown under the bus. If Icannot remember any particulars aboutthe failed part, how can I expect theEngineer to be able to rememberanything and support me? He may havea dozen projects and fabricators underhis purview at any one time. It isunreasonable to think that he would beable to remember every detail of all theprojects he supervises. I, at least, livedwith the project. The Engineer reliedon me and my expertise, but cannot beexpected to remember any small detailshe did not directly work with.
What if It Isnt a Weld YoureInspecting?
As part of my duties, I am alsoexpected to inspect the coatingoperations. Most third-party inspectorsworking for DOTs are required toinspect coating operations, includinggalvanizing. (I cannot remember acontract where the third-party QA CWIdid not have to also inspect the shopcoatings operation.) Some states alsorequire the inspector to have a NationalAssociation of Corrosion Engineers(NACE) Level 1, 2, or 3 CoatingsInspector certification. However, mostonly require the supervisor to have aNACE Level 3 CIP certification. I donot have any NACE certifications, butI do have documentable experienceperforming basic coatings inspection.The client deems me qualified toperform coating inspections, includingthe blast cleaning, at least to the levelthey desire, as part of my inspectionduties.
Now there is nothing in the AWSCode of Ethics, Rules of Conduct, andPractice that addresses coatingsinspection. However, we do havegeneric requirements for honesty inArticles 11.1, 11.2.4, and 11.2.6.
Recently, I heard about a CWI QCinspector at a large bridge fabricationfacility who forged a paint report andhanded it to the QA inspector. The QCinspector had reportedly altered thedates and the piece number on thereport, but left the dry film thicknessvalues and paint batch numbers of theoriginal girder on the year-old report.
Unfortunately for that QC inspector,the QA inspector somehow recognizedthe old report, dug it out of the files,and compared it to the other one byholding both copies up to a light. (Howis that for a winning the bad lucklottery?) The QC inspector reportedlywas then asked if this was his report,and he asserted that it was. Reportedlyhe was asked again, and affirmedagain. Then he was confronted with theoriginal.
I have heard that the CWIsubsequently resigned his position. Insome jurisdictions submitting a falsedocument for filing is a seriousmisdemeanor or even a felony. Thereare federal funds involved in thisbridge contract, so there could also befederal criminal charges. What willhappen to this individual has yet to beseen. As for the AWS Code of Ethics,Rules of Conduct, and Practice,Section 11.2.4 applies even though itwas paint inspection instead ofinspecting welds. In this case, coatingsinspection was part of the CWIscontractual duties on the project.Therefore, there may yet be AWS Codeof Ethics violation charges in this case.
Other Situations
The ethical dilemma doesntalways start with computer-generatedforms. Some ethical questions may justbe a problem of perception. A simpleWelding Procedure QualificationRecord (WPQR) is rife with possibleethical traps. As a QA CWI, Iwitnessed all the welding, performedthe postweld visual inspection, andperformed the macro-etch testing, but Idid not witness the removal of themechanical test specimens from thewelded coupon assembly, themachining of the backing bar or of thespecimens, nor the bend and tensiletesting. I did not see the Charpy V-notch specimens machined or tested.All the machining and mechanicaltesting was performed by a third andfourth party. Yet I was the one requiredto sign off on the WPQR and send it tothe customer. In that case, I trusted thelab involved, but the staff there mademany data entry mistakes when theytransferred my handwritten notes ontotheir beautiful computer-generatedform and sent it out for my signature. Ihad to send it back for correctionbefore I would sign it. Therecommended PQR forms in Annex L

of D1.5, Bridge Welding Code, seem toallow inspectors to be very specificabout what they have witnessed.However, not so with the WelderQualification Form (L-5). The CWIsignature anywhere on the form couldlead someone to infer that the CWI hadsigned the welder off.
In another instance, I was thethird-party witness at a testing lab thatdid not have a tensile machine strongenough to pull the reduced sectiontensile specimen required for a majorhigh-rise project, and they had to cutthe reduced section tension specimenin half lengthwise and pull fourcoupons instead of two. (This was donewith the approval of the customersengineer.) As you can imagine, thiscreated a lot of extra work. I asked thetesting lab owner how he does this typeof testing normally. Well, if youwerent here to witness it, we wouldhave just penciled it in. What anastounding answer! To drive home whyI believe he was being truthful and not
just giving me a smug answer, theejecta area near their Charpy testingmachine had a whole pile of rustedspecimens laying in the corner on thefloor. Now, if you do not pick up thespecimens each time, examine andmeasure them, how do you report onthe percentage of shear and thepercentage of lateral expansion?
Because most times you do nothave to report anything but the impactvalue at temperature, this might havejust been a housekeeping issue.However, this lab does work for abranch of the government that usuallyrequires the additional data. So thisobservation, combined with theoutrageous response to the question,made me suspicious.
I was able to find my specimens,because they were the only shinyspecimens there. Think about it, if youdo not trust the testing lab, shouldntyou worry about signing your name tothe rest of the report?
Summary
The point of all this is that intodays age not every ethics issue is ascut and dried as those in the past. Iadvise that you think things throughbefore signing your name to electronicand/or paper documents. As a CWI,you need to not only adhere to theAWS Code of Ethics, Rules ofConduct, and Practice, but also payclose attention to your own moralcompass.

By Nancy Glickman and Salahuddin Razi
Moraine Valley Community
College, Palos Hills, Ill., is the only
community college in the state with a
nondestructive examination (NDE)
training facility. Offering both classes
on campus and customized training for
businesses, this nationally recognized
program provides training to meet the
American Society for Nondestructive
Testing (ASNT) certification procedure
SNT-TC-1A and can be modified to
meet the requirements of CP189 and
NAS410.
Through this program, the college
is helping the unemployed and
underemployed, veterans, and career
changers return to work. Incumbent
workers looking to progress in their
careers also can receive advanced
training. Lewis Universitys aircraft
mechanics degree program also uses
the programs high-quality training
with hands-on experience.
The NDE Program
The courses taught at Moraine
Valley provide the required training for
Level I and Level II students in SNT-
TC-1A. The program includes
theoretical and practical training
needed for different levels of
certification. Faculty members are
required to be certified to meet the
NDT Level III requirements of SNT-
TC-1A and hold either the Level III
certificates issued by ASNT or
equivalent certificates issued by other
certifying organizations. Additionally,
they are expected to stay current with
technological changes in NDE by
attending conferences, seminars, and
other technical training.
The colleges laboratory has a vast
collection of test samples, including
welding samples, for instructional
purposes. Sometimes students can
work with test specimens similar to

those they anticipate will be used in
their careers. However, all students are
expected to test a variety of different
specimens and are graded at levels
appropriate to their certification.
Students are required to get enough
practice to perform the NDE tests since
NDE is essentially an applied
discipline.
Why Is Training Essential?
While NDE is used in numerous
fields, including aircraft inspection,
building construction, power plants,
power generation, shipbuilding, and
drilling rigs, all manufacturers or
construction fields could benefit from
nondestructive techniques to ensure a
high-quality product is being produced
and is suitable for continued use.
As nondestructive examination is a
general-purpose method used to inspect
various parts, it is essential
professionals have a solid
understanding of the technology and
techniques that will be used, as well as
knowledge of the materials on which
these methods are employed.
Students in Moraine Valleys NDT
program study theory, but they also get
plenty of hands-on practice.
Nondestructive examination is built on
strong foundations of physics,
chemistry, and math. Understanding
these basic principles is critical to
becoming a competent NDE
professional. Without this knowledge,
students will find they are severely
handicapped in the NDE profession.
Using a computer to write reports and
acquire data also is becoming essential
for all NDE professionals. The college
encourages students to access
information online to get comfortable
with using a computer and offers many
credit and noncredit programs to
increase skills in this area.
Existing Training and Plans
Moraine Valley Community College
enables students to complete basic
training to enter the job market or
improve skills needed for a promotion.
After completing training and passing a
qualifying examination, the college
certifies that the students have
completed the required hours of formal
training for Level I or Level II
certification in the methodology studied.
Students then are prepared to take
the next step in their professional
careers. Nondestructive examination
certification programs also require
students to complete a significant
number of on-the-job training hours
before taking their certification tests.
Certification is given through the
employing company.
Moraine Valley offers several
courses in NDT. Radiography courses
usually are preceded by a Radiation
Safety class. Regulatory bodies at state

and federal levels require all personnel
performing radiography to be trained in
the fundamentals of radiation
protection so they can adequately
protect themselves and the general
public from hazards associated with
radiation.
Radiography can be performed
either with an X-ray source or a
radioactive source (usually Ir-192 or
Cobalt 60). Both methods have
advantages and disadvantages, but both
can find defects and are widely used
for inspection of welds. Radiography
has the advantage of providing a visual
record of the quality of the weld being
inspected, but the increasing use of
computers to scan images and analyze
defects is impacting this method
Fig. 1. Digital radiography is becoming
more popular and is expected to
replace the conventional film
techniques.
In the field of ultrasonic testing,
students learn on the equipment
commonly used for performing the
inspections, which allows them to
succeed in the job market Fig.2.
Moraine Valley plans to introduce
phased array inspection, but these
courses are in development.
Ultrasonic testing has long been
used for weld inspections and, until
recently, had the disadvantage that it
did not produce a permanent record of
the inspection. However, with the
increased use of scanners, phased array,
and computerized equipment, making
visual records is easy additional
support for the future of inspection
technologies becoming more heavily
influenced by the improvement of
computer technologies.
Magnetic particle and dye
penetrant testing historically have been
used as surface inspection techniques
primarily in the inspection of fillet
welds and as supplementary
examination of surface defects in
complete-joint-penetration welds.
These techniques historically have
been very successful in detecting
surface discontinuities and, therefore,
have been widely used. The operator
does not need as much training, and the
equipment/materials are less
sophisticated.
Eddy current testing and visual
testing techniques are taught based on
need and demand for the course.
Students studying these techniques also
use the large collection of the colleges
samples so they can learn about the
different materials they are likely to
encounter in their work.
Collaboration betweenCollege and Industry
Moraine Valley maintains an
Advisory Board composed of
administrators, faculty, and members of
business and industry who have been
instrumental in helping design a four-
course core program that prepares
students for entry-level technician
positions. This group, along with local
businesses, makes up the 28 partner
companies that review rsums of
course completers and employ program
graduates. The board also assists
Moraine Valley with staying current in
the industry by assessing needs and
adjusting the curriculum to address
those needs.
Local and national job
opportunities are plentiful in NDE.
After graduation, most students have
found employment at companies that
perform in-house NDE, including
foundries, aircraft repair, and
manufacturing. A significant number of
students are employed at independent
laboratories and facilities where they
can get a wide range of experience.
Those who like to travel or are looking
to relocate should easily find work in
other areas of the country. The average
annual salary for NDE technicians in
Chicago is $52,000 (www.indeed.com,9/4/12). As in other skilled trades, the
NDE industry is experiencing many
retirements by Baby Boomers. That,
coupled with the opening of additional
pipelines and federal- and state-funded
infrastructure projects, means that jobs
are being created for younger workers.
In this day and age, NDT
absolutely is a solid career choice. Like
anything else, it can be what you make
of it, said Rich Flores, a Moraine
Valley NDT program graduate. You
can be the best assistant in your
company or a fully certified technician
across the board. Your personal drive
will be the deciding factor. Like most
crafts, there are inherent risks. You can
expect to get dirty in the field as well
as spend time preparing reports back in
the trailer. You will remain reasonably
physically fit and will be trained to be
observant, sharp, and professional. At
the end of the day, when you discover
that indication that could have been a
serious failure, it is very rewarding. All
of this is the result of your decision to
begin your career in NDT, and the
program at Moraine Valley is the best
place to start. .
