Question (1): May a procedure qualification record subject to the variable QW-407.1(a) which

qualified P-No. 8 to P-No. 8 with no PWHT support a WPS with PWHT?

Reply (1): QW-407.1(a) does not apply to P-No. 8 materials. See QW-407.1(b).

Question (2): Would application of controlled and monitored heat to the weld and surrounding

area for the correction of distortion in P-No. 8 material be considered a PWHT operation?

Reply (2): See QW-407.1(b).

Note: This interpretation originally appeared in Volume 54. The “P8” has been corrected by

Errata to read “P-No. 8”.

Interpretation: IX-04-04Subject: QW-401.3 Supplemental Essential Variable


File No: 03-1246

Background: A WPS is supported by three PQRs. Two PQRs are recorded on 12 mm and 28.5mm thick coupons using tensile, bend, and impact testing specimens. A third PQR was made

using 5 mm thick plate using the same welding parameters, but only impact specimens were

tested.

Question (1): May these PQRs be combined to support a WPS for welding 2.5 mm through 57

mm material requiring notch toughness testing?

Reply (1): No.

Question (2): May these three PQRs be combined to support welding base metal thicknesses



of 4.8 through 57 mm with or without notch toughness?

Reply (2): Yes.

Note: This interpretation originally appeared in Volume 54. The “WP” in Question (1) has

been corrected by Errata to read “WPS”.

Interpretation: IX-04-11Subject: QW-451.1, Procedure Qualification Thickness Limits and Test Specimens and



QW-202.4, Dissimilar Base Metal Thicknesses

Date Issued: December 22, 2004

File No: 04-599

Background: A procedure qualification test coupon using the same P-Number material and

consisting of two plates of different thicknesses are welded together, where the thicker of the

two plates (T2 = 1-1/2” thick) has been tapered on a 4:1 taper down to the thinner plate

thickness (T1 = 1” thick).

Question (1): Does this test coupon qualify the WPS for a base metal thickness range of 3/16”

to 8”?

Reply (1): See Interpretation IX-86-43, Question (2).

Background: A procedure qualification test coupon using the same or different P-Number

materials and consisting of two plates of different thicknesses, T2 = 1-1/2” thick and T1 = 1”thick welded with a single process. The thicknesses meet on the same plane with neither plate

being tapered. The joint is welded in accordance with the sketch below.

Question (2): Does this test coupon qualify the WPS for both base metals for a thicknessrange of 3/16” to 8” on both sides of the weld joint?

Reply (2): Yes.

Question (3): Does this test coupon qualify the WPS for both base metals of different P

Numbers for a thickness range of 3/16” to 8”?

Reply (3): No. QW-202.4 requires both base metal thicknesses be in accordance with QW-

451.1. Base metal T1 is qualified 3/16” to 2” and base metal T2 is qualified 3/16” to 8”,

Question (1): Does QW-409.1 require that the highest heat input, to be recorded on the PQR, becalculated on the parameters used at the location where the HAZ impact specimens are removed?

Reply (1): No.

Question (2): GTAW is a non-consumable electrode welding process that would record zero



for the “per unit length of electrode” in QW-409.1(b). Therefore, can the weld volume method

Reply (1): No.

Question (2): Are the requirements of QW-150 and QW-451 satisfied if the WPS and this PQR

supports is limited to a base metal thickness range of 3/16 to 2 inches instead of a base metal

thickness range of 3/16 to 2-1/4 inches that would have been permitted had a sufficient number of

Interpretation: IX-07-05Subject: QW-100.3 and QW-420.1, Change of P-No. as an Essential Variable with

Respect to Reassignment of P-No.5 into P-No. 5A, 5B, and 5C (2004 Edition)


File No: 04-600

Background: A welding procedure was qualified in 1975 (without impact testing) for joining P-

No.5 materials, using SA-213-T9 in the PQR test coupon. P-No.5 has since been deleted, and

CrMo materials have been reassigned to P-Nos.5A, 5B, and 5C, with SA-213-T9 being assignedto P-No.5B. It can be demonstrated that SA-213-T9 is now designated as a P-No.5B material.

Question (1): QW-100.3 allows the continued use of welding procedures qualified under previous

Editions and Addenda of the Code without revision to include any variables required by laterEditions and Addenda. Is it the intent of QW-100.3 to allow the use of this WPS to join P-No.5A,

.P-No.5B or P-No.5C materials without requalification when toughness is not a consideration?

Reply (1): No. QW-100.3 applies when later Code Editions and Addenda have added new

variables for a given welding process. While this WPS can be shown to be qualified for welding

P-No.5B materials to each other, it is intended that the WPS be editorially revised to show

applicability of the WPS to the originally qualified materials under the material grouping



assignment found in the applicable Edition and Addenda of Section IX. See QW-420.1 and QW-

200.2(c).

Question (2): Is it the intent of Section IX that the WPS described above is acceptable for joiningall materials previously assigned P-No.5?

Reply (2): No. Based upon the original PQR, the WPS is qualified only for joining materials

assigned to P-No.5B under the current Section IX rules. See QW-403.13.

part of the original PQR, but followed the conditions of the original qualification?

Reply (1): Yes.

Question (2): If the tests and data noted in Question 1 are added to the PQR, wouldrecertification, including date, be required?

Reply (2): Yes. All changes to a PQR require recertification (including date) by the
