I. SCOPE

PURPOSE

This CBA provides guidelines for safe welded fabrication. These guidelines are in compliance with legallyrequired, as well as local and nationally recognized construction codes and P&G practices. This CBA alsoprovides welding management guidelines.

A written site welding system must be implemented for control of welding quality consistent with this and otherP&G Welding CBAs. Specific System requirements can be found in WE02.

NOTE requirements in this document also apply to brazing activities.

Project managers, site engineers, welding inspectors, purchasing managers, and the site welding systemowner need to use this CBA. This will help to ensure that welding related activities are done properly and costeffectively. This includes design, fabrication, erection, examination, testing and inspection. Utilizing this CBAwill also help increase site reliability.

Welding is a skill that requires extensive training and experience. Continual use of welding skills is needed tomaintain the expertise in metal joining. A minimum number of welders should be qualified consistent with thequantity and type of welding processes and joints to be done. For a qualified welder to maintain codecertification and quality requirements, a considerable number of hours should be devoted to welding. Workerswho only occasionally weld have difficulty meeting qualification requirements of legal construction codes andincrease the maintenance or construction costs to the site due to rework and repair.

Welding examination, testing and inspection is necessary to help ensure proper execution. It is required bythe construction codes and standards.

II. RESOURCES

P&G Corporate Welding & Fabrication Engineering (CWFE) is the owner of this CBA. Contact CWFE forguidance and clarifications. For Welding Engineering Support go to http://vcs.pg.com/ext/GEX/Weld/default.aspx

III. APPROACH

1. COVERAGE

This Welding CBA assists with implementation of the company global policies of:

a. P&G insists on safe operation, and

b. P&G operates within the law.

Sites must have a written system to implement this Welding CBA. This CBA covers the followingwelding topics for fabricated equipment, systems and structures in company installations: design,fabrication, on-site construction, site maintenance (rework/repair), failure analysis, inspection andtesting.

Sites must comply with the requirements of all National, Federal, State, and local construction codesand standards having jurisdiction.

The following paragraphs contained in this Welding CBA and other Welding CBAs assure compliancein most locations.

NOTES:a. In some countries and/or regions, governmental agencies or a P&G regional resource may

have some of the responsibilities shown above.b. The Welding System Owner may be a Welding Inspector (if qualified/certified as both).

3.3 Corporate Welding Engineering Global Responsibility:

a. Determine which countries require P&G Welding Engineering oversight for pressure vessels,hazardous systems and/or building integrity versus utilizing Government providedagencies/systems to insure code compliance.

b. For fabricated equipment requiring P&G Welding Engineering oversight*:- Specify training and qualification requirements for field welders and welding inspectors.

- Provide concurrence to the selection and approve the P&G certification of Welding Inspectors(both P&G and contractor).- Development of P&G standard welding practices and concurrence to deviations by

businesses* This equipment includes: tanks, PVs, piping and other components fabricated from materialsother than mild steel or 300 series stainless steel; equipment for hazardous service; field erectedtanks; sanitary fabrication; and equipment where reliability is unusually critical.

Verification of correct execution of welding activities must be performed by a properly qualified andcertified welding inspector on a frequency that assures construction code and company standardscompliance. Details of certification and responsibilities of the Welding Inspector are defined in CBAWE03 Welding Inspectors.

5. WELDING PROCEDURES

Practices for Welding Procedure Qualification and Use are located in CBA WE08.

6. WELDER PERFORMANCE QUALIFICATIONS

Practices for qualification and re-qualification are located in CBA WE04 Performance Qualification ofWelders.

7. PROCUREMENT OF FABRICATED EQUIPMENT

All fabrication inquiries and purchase orders must include weld quality acceptance criteria; normallycontained in nationally recognized construction codes and standards. WE05 Specification for

Purchase of Fabricated Equipment, Structures and Components, should be a part of the standardsprovided.

8. MAINTENANCE OF EQUIPMENT

When maintenance involving welding related processes is necessary to be performed on fabricatedequipment, it is defined as either rework or repair. Rework is defined as restoring the equipment tothe original condition and specification(s), while repair makes the equipment functional, but not to theoriginal condition and specification(s). Maintenance of equipment must follow the outline and guide(s)shown in P&G Welding CBA WE07, Fabrication Guidelines for Maintenance of Equipment.

9. SAFETY

There are hazards associated with welding, brazing and cutting. As a minimum, legally required, localand nationally recognized safety standards/codes must be followed. Welding/Hot Work permits mustbe used to make certain proper safety precautions are taken before and during welding operations.

One industrial standard used in the area of welding safety is the American Welding Society (AWS)Standard, American National Standard ANSI/ASC Z49.1 "Safety in Welding and Cutting". Thisstandard covers aspects of safety and health in the welding environment, emphasizing oxygen gasand arc welding processes. It contains information on protection of personnel and the general area,ventilation, fire prevention and protection, and confined spaces. ANSI/ASC Z49.1 "Safety in Weldingand Cutting" is a voluntary consensus standard that has been developed in accordance with the rulesof the American National Standards Institute. Other welding safety standards may exist in regionsother than North America.

APPENDIX A - When Does P&G Welding & Fabrication Engineering Need to be Involved in a Project?

"Involvement" starts with a discussion to determine what and how, if anything, needs to be done byP&G Welding Engineering. The "Project" may be a capital project, a maintenance project, or acombination of both. There is significant opportunity to save capital and/or improve project results byusing this process.

CRITERIA: If "YES" to one or more, then contact Welding Engineer.1. New technology at the site?2. Not sure that the site has the skills or experience for the review3. Need construction welding inspector (CWI or equivalent)4. Project with a 10 or more contractor welders and/or more than $100M worth of vendor fabrication5. Proprietary or special welded fabrication6. New fabricators, not on P&G "pre-qualified" list7. For tanks, pressure vessels, piping, machinery, etc.:

- materials other than carbon/mild steel or austenitic stainless steel

- Hazardous service (OSHA 1910.119, pressure > 300 psi, etc.)- FDA (USA) or sanitary fabrication- reliability of welded equipment is unusually critical

8. Field erected tanks

NOTE: When the project is a reapplication or direct repeat of something recently completed, theneed for or scope of involvement will be reduced or in some cases eliminated. However, a shortdiscussion about the need for involvement is still appropriate.
