S9074-AQ-GIB-010/248 Rev 1
5-2.3.1 Welding Personnel Training in Workmanship and Visual Acceptance Criteria. Training shall be administered in accordance with a program approved by one of the activity’s NAVSEA T9074 -AS-GIB-010/271 certified level III nondestructive test examiners or other NAVSEA-approved individual. This program shall include: a. A written procedure covering all aspects of this training program and associated responsibilities. A copy of the procedure shall be provided to the authorized representative for approval. b. Training in workmanship and detailed visual inspection requirements of all fabrication documents to which welding is performed. For pipe welders performing socket joints or one-sided groove joints not subject to RT, training and examination shall specifically include all of the following: (1) The need to visually check the pipe ID immediately after joint completion when any portion is accessible (2) Pipe ID acceptance criteria for all joints involved (e.g., sockets, backing rings, consumable inserts, no backing) (3) How to obtain final pipe ID VT before welding other joints that may render an ID inaccessible (4) For socket joints over 2 inches NPS, requirements for pipe-to-fitting diametrical clearance and engagement and measurement methods and, when applicable, conditions for increasing fitting leg size c. Examinations covering detail workmanship and visual inspection requirements to be passed by each person with a grade of no less than 75 percent. d. Approval of items (a), (b), and (c) by the level III examiner or other NAVSEA-approved individual. e. Maintenance of examination records for each welder or welding operator, which shall include: name, fabrication/acceptance standards covered, date of test, results of test (in percent), and certifying signature of test administrator. f. Re-testing of each welder or welding operator every 3 years. g. Auditing of the entire program specified in 5-2.3.1 by the level III examiner or other NAVSEA-approved individual to ensure adequacy. Audits shall be conducted at least once every 2 years and, where applicable, the audit shall be extended to specifically address titanium welders. 5-2.3.2 Robotic Welding Operator Requirements. These personnel shall also be trained and tested in accordance with a program established by the activity meeting the following requirements, as applicable, for each procedure: a. Identification and use of robotic welding system equipment. b. Routine operator maintenance of the robotic welding system equipment. c. Operation of the robot teach pendant, control station, or both to execute, modify, or stop a production weld or program cycle. d. Creation or modification of robot programs and routines. e. Use of adaptive welding technologies. f. Use of audio and vision aids (e.g., weld puddle cameras) for mechanized robotic welding. 5-2.4 ALTERNATIVE QUALIFICATION METHODS. As an alternative to 5-2.3.b, qualification requirements for welders or welding operators shall be satisfied as follows: a. Welding a production weld that is RT or UT inspected and found satisfactory. Approval to use this method of establishing performance qualification must be obtained for each welder and welding operator from the authorized representative prior to start of the individual’s production work. This m ethod is not applicable to S-51, S-52, S-53, and S-53A materials. b. Welding satisfactory procedure qualification test assemblies subject to the limitations of performance qualification in Chapter 5. c. Qualifying in accordance with the requirements of other U.S. Government agencies, ABS, or ASME within the limits imposed by this document, provided evidence of qualification is verified and approved.
