A-4.2.2 Alternative Qualification Methods. As an alternative to A-4.2.1.a, qualification requirements for FS operators shall be satisfied by FSW, FSP, or repairing satisfactory procedure qualification test assemblies. A-4.2.3 Qualification Limits by Material, Thickness, and Filler Material. Performance qualification limits shall be as listed in tables A-4 and A-5. A-4.2.4 Requirements for Special Welds. For special welds, the proposed performance qualification program shall be included with the procedure qualification test data submitted for approval (see A-3.2.2). A-4.2.5 Repair to Test Assemblies. Test assemblies may not be repair welded. A-4.2.6 Maintenance of Qualification. A-4.2.6.1 Renewal of Qualification Due to Lack of Process Use. Renewal of qualification due to lack of FS use not exceeding 1 year shall be made by making only one test assembly with all the essential elements used on any of the FS operator’s previous qualification test assemblies. The test assembly shall be nondest ructively inspected in accordance with table A-2 and destructively tested by one macro-etch specimen, one root bend, and one transverse weld tensile test in accordance with A-3.5. Successful completion of this test will re- establish the FS operator’s qualification for all conditions for which the operator previously qualified with the FS variant employed. Renewal of qualifications under all other conditions shall be in accordance with initial qualifications required by this document except where lesser requirements are approved by the authorized representative. A-4.3 PERFORMANCE QUALIFICATION TEST REQUIREMENTS. A-4.3.1 FSW and FSP. Test assemblies shall be friction stirred with a qualified FSW or FSP procedure, as applicable. A-4.3.1.1 Repairs to Friction Stirred Material. Personnel performing FS repair of friction stirred material shall be qualified for FSW or FSP, as applicable. Qualification of personnel performing fusion weld repair of friction stirred material shall be in accordance with Chapter 5, as applicable, for the fusion welding process involved. A-4.4 TEST AND EVALUATION OF QUALIFICATION TEST ASSEMBLIES. This section provides the requirements for evaluation of qualification test assemblies. The tests required for each assembly are as specified in table A-2. A-4.4.1 Nondestructive Inspection. A-4.4.1.1 Visual Examination. Visual examination shall be performed prior to removal of flash and shall be performed for FS pass surface geometry and surface soundness in accordance with NAVSEA T9074-AS-GIB-010/271. A-4.4.1.2 Nondestructive Test Performance. Nondestructive testing shall be performed in accordance with NAVSEA T9074-AS-GIB-010/271. Test assembly welds shall be 100-percent inspected except as permitted by A- 4.4.1.3. A-4.4.1.3 Acceptance Standards. Acceptance standards for liquid penetrant testing, visual examination, radiography, and UT shall be based on the requirements of MIL-STD-2035, class 1. Areas identified as discard in the qualified weld procedure need not be evaluated. A-4.4.2 Destructive Tests. Required specimen preparation, dimensions, and mechanical testing shall be in accordance with A-3.5. A-4.4.2.1 Bend Tests. Acceptance standards for bend tests shall be as specified in A-3.5.2.2. A-4.4.2.2 Macro-Etch Specimen. Specimens shall be as specified in A-3.5.2.3. A-4.5 DATA AND RECORDS. This section provides the requirements for performance qualification data accumulation and maintenance of records.
