b. Qualify the proposed brazing procedure by brazing test assemblies and performing nondestructive and destructive tests in accordance with the requirements of this section and submit results per 6-3.3. Except as noted herein, procedure qualification tests are not required for oxy-fuel manual torch brazing with base materials, brazing alloys other than F-101A and F-102A, and flux combinations specified by table 7-12; F-101A and F-102A brazing alloys require qualification. Qualification tests shall be performed for manual torch brazing procedures that specify materials not classified in table 7-12 and for all other brazing processes, including the following: (1) Mechanical-torch (2) Furnace (3) Induction (4) Electrical resistance (5) Dip brazing – salt and flux bath 6-3.1.1 Qualification Brazing. Personnel brazing qualification test assemblies shall be regular employees of the activity (i.e., not subcontractors or temporary specialists) and under the full supervision and control of the activity. Brazing of qualifi cation test assemblies should be accomplished at one of the activity’s sites, with the activity’s brazing equipment or equipment similar to that being acquired by the activity; if brazing is performed at a site other than the activity’s site, the activity’ s employee responsible for developing the procedure being qualified and assuring that it is correctly implemented shall also be present and directing the activity’s brazer/operator during all brazing. 6-3.2 CERTIFICATION OF QUALIFICATION TESTING. After testing, the responsible official of the activity shall certify that the tests and the test results meet all requirements of this document. Inasmuch as the activity is responsible for the quality of its work as well as that of its subcontractors, the activity shall submit qualification tests and data of its subcontractors only after careful review and verification of their completeness. Qualification tests and data containing deviations from requirements may be submitted if such deviations are identified and the technical justification for each deviation is provided. When brazing to the requirements of the ASME code is specified or approved, the specific component or system specifications or approval letter shall be identified. Procedure qualification previously prepared for other Government agencies, ABS, ASME, or other established regulatory codes may be used, provided qualification testing and approval (by the other Government agencies or regulatory bodies) occurred prior to the activity’s invitation for bid or request for proposal. It is the intent of this provision that certified qualification data acquired by these agencies be considered acceptable proof of qualification. Such data shall be submitted for approval as requested in 6-3.3. 6-3.3 APPROVAL OF QUALIFICATION TEST DATA AND PROCEDURE SUBMISSION. When qualification testing is required by 6-3.1, the activity shall submit the qualification test report of 6-3.4 to NAVSEA or its authorized representative for approval. Approval shall be obtained prior to production brazing. Procedures are the activity’s responsibility but shall be submitted for review, including upon initial preparation, even where qualification testing is not required. Resubmission of procedures is only required for changes involving (1) requalification or (2) a reduction in joint classification (see 6-2.1.a(1)) or nondestructive testing. Brazing procedure submittal does not mitigate the performing activity’s responsibility for conformance with the requirements of this document. 6-3.3.1 Requirements. The following requirements shall apply for the brazing procedure and the brazing procedure qualification test report. a. Brazing procedure qualification test report. The brazing procedure qualification test report shall be in accordance with 6-3.4. b. Brazing procedure. The brazing procedure shall be in accordance with 6-3.8. 6-3.4 TEST REPORT. The procedure qualification test report shall include the essential elements of the brazing procedure as specified in 6-3.8, with the values used for qualification, and the results of the destructive and nondestructive tests specified in 6-3.9.
