5-2.5 QUALIFICATION LIMITS BY BASE MATERIAL, FILLER MATERIAL, AND PROCESS. Multiple performance qualifications may be attained by qualifying as outlined in table 7-8. When radiography is used for evaluation, S-1 material may be used when using filler metal groups A-1 through A-8, and A-34, A-42, A-43, and A-45; other base material/filler material combinations shall be from a qualified similar or dissimilar metal groove welding procedure. When bend tests are used for evaluation, the base material shall be compatible to the filler material with regard to weldability and shall be of comparable strength. Utilization of commercially equivalent filler material (see 5-6.2.a) is permitted for performance qualification tests. 5-2.6 QUALIFICATION LIMITS BY POSITION AND JOINT TYPE. The positions and joint types for which a test assembly qualifies are as shown in table 7-9; for specific test assemblies, see 5-3 and table 7-10. 5-2.7 REQUIREMENTS FOR SPECIAL WELDS. For special welds, the proposed performance qualification program shall be included with the procedure qualification data submitted for approval (see 4-2.5). 5-2.8 REPAIR TO TEST ASSEMBLIES. Test assemblies, other than those for automatic, mechanized, and robotic welding, may be repair welded under the following conditions: a. Cracks (other than crater cracks), root oxidation, burn-through, and backside defects per figure 7-14, note 3 and rejectable titanium weld color per 4-5.1.1.1 shall not be repair welded. b. Only one cycle of repair welding is permitted and the repair shall be recorded on the permanent test records. c. All test results, including a description of the nondestructive test results that failed to meet the requirements, shall be recorded on the permanent test record. Qualification test assemblies for automatic, mechanized, and robotic welding shall not be repair welded. 5-2.9 RETESTS. If a performance qualification test assembly fails to meet the applicable requirements, retests may be allowed under the following conditions: a. One retest may be made without further training for each test assembly that failed. b. Subsequent retests may be made for each test assembly that failed to meet the requirements if the welder or welding operator has had at least 4 hours of training or practice designed to correct the reasons for previous failures. 5-2.10 TRANSFER OF QUALIFICATION. Transfer of performance qualification from one activity to another is not permitted without specific approval by the authorized representative. 5-2.11 MAINTENANCE OF QUALIFICATION. Each activity shall establish that an active qualification status is maintained for each qualified welder or welding operator. This requirement pertains only to process qualification without regard to the initial qualification limitations of 5-2.5 and 5-2.6. For each qualified process, evidence of maintenance of qualification, consisting of at least one verification of process use (i.e., activity certification of the use of shielded metal arc, gas metal arc, etc.) within 6 months after the month the person last used the process, shall be maintained. In addition, for titanium welders and welding operators, at least one verification of the process being used on titanium base metal within this 6-month period shall also be maintained. Process use shall be (1) production welding, (2) completion of one figure 7-16 weld tested per 5-4.1.1 and 5-4.2.2, or (3) completion of one previously performed butt qualification test weld, other than figure 7-16, that is visually inspected per 5-4.1.1. In cases (2) and (3), the test position and filler material may be any for which qualification is held with the process, except that the flat position shall not be used, unless only flat position qualification is held for the process. Alternative, equivalent verification welding can be used for process use if approved.
