CHAPTER 5 WELDING PERFORMANCE QUALIFICATION

5-1 SCOPE. This chapter provides the requirements for qualification testing of welders and welding operators. For friction stir, including repair of friction stirred material, specific qualification requirements shall be per Appendix A in addition to the general requirements of this chapter. Also included are the requirements for qualification records with suggested record format and forms for data accumulation and reporting. 5-2 GENERAL REQUIREMENTS. 5-2.1 RESPONSIBILITY. When this document is specified by the applicable fabrication document, each activity shall establish that each welder and welding operator to be employed for welding has been qualified by demonstrating an ability to produce welds that meet the requirements of this chapter. Performance qualification is not required for resistance welding per 4-4.3 or stud welding; however, welding personnel shall be trained in the proper application of the welding procedure and all governing acceptance criteria. 5-2.1.1 Waiver of Qualification Tests. Qualification tests of welders working on assemblies, the possible failure of which is remote and would not result in danger to the ship, plant, or structure, such as identification plates, galley equipment, furniture, fixtures, and miscellaneous outfitting, may be omitted provided this omission is permitted by the applicable fabrication document or is approved. 5-2.2 PREREQUISITE. As a prerequisite to performance qualification, each activity shall have qualified procedures in accordance with Chapter 4 for all applications for which performance qualification is intended. Although it is essential that the welder be cognizant of the contents of the qualified procedures, this requirement shall not be interpreted to mean that the performance qualification must be accomplished in accordance with any qualified procedure. Performance qualification shall be accomplished as specified in this chapter. Where multiple performance qualifications are attained as specified in 5-2.5, the welder shall be familiar with the content of each involved procedure. If subsequent procedure qualification data approvals are obtained for procedures for which the multiple performance qualification of 5-2.5 would apply, the qualified welder shall be familiarized with the contents of each new procedure. 5-2.3 METHOD OF ESTABLISHING QUALIFICATION. Qualification of welding personnel requires satisfaction of all of the following conditions: a. Each welder and welding operator shall know the workmanship requirements and visual inspection requirements of all fabrication documents to which the welder will be working. To ensure this knowledge, each welder and welding operator shall be trained and tested in accordance with a program meeting the requirements of 5-2.3.1. For robotic welding, the requirements of 5-2.3.2 shall also apply. b. Assurance that each welder and welding operator has satisfactorily welded the applicable performance qualification test assemblies. c. Inspection of each qualification test assembly in accordance with the requirements of this chapter. d. Evaluation of the results of either the destructive or nondestructive tests, or both, in accordance with the applicable standards unless otherwise specified in this document. e. Maintenance of current records of the extent of qualification for each welder and welding operator (see 5- 5.1).
