Prior to production welding, welding procedures in accordance with the requirements of MIL-STD-248 and this document shall be prepared by the activity. Welding procedures shall assure conformance with this document and shall be submitted for information when procedure qualification test data are submitted to the authorized representative for approval (see 4.2.1.2) or whenever the welding procedures are revised. Procedures qualified in accordance with NAVSEA 392- 0755 may be used for welding of seal welds without separate qualification in accordance with MIL- STD-248. 4.2.1.1 Conditions governing welding procedure qualification tests. Welding procedure qualification tests are required where fabrication drawings or specifications invoke this document, except qualification tests are not mandatory where both of the following conditions are met. (a) Either classes M-1 category C. M-2 category C. A-4, P-2 (except for joint designs welded from one side only with no backing), or T-2 weldments are involved, and the base materials being joined are of the same "S-number" group (except 5-11A. S-11B. S-11C. S-51 to S-53) listed in table I (or a comparable ASME P-number group, if approved) and the corresponding filler materials listed in table III are used with the following manual or semi-automatic processes.
(1) Shielded metal-arc. (2) Gas tungsten-arc. (3) Gas metal-arc. (4) Flux core. (5) Submerged-arc. (6) Oxyacetylene where group S-1 materials 3/16 inch or less in thickness are joined.
(b) Fabrication entails welding of assemblies, the possible failure of which is remote and would not result in danger to ship personnel, shipboard components or equipment, or ship structure. Items in this category include but are not limited to name plates, galley equipment, furniture. fixtures, and tack welds.
