AWS B2.1-8-321 – Standard Welding Procedure Specification for Naval Applications (SWPS-N) for Gas Tungsten Arc Welding with Consumable Insert Root of Austenitic Stainless Steel (S-8), 1/8 inch [3 mm] through 1-1/2 inch [38 mm] Thick, MIL-3XX, in the As-Welded Condition, Primarily Pipe for Naval Applications

The data to support AWS B2.1-8-321:2018 for Naval Applications (SWPS-N) have beenderived from the above listed Procedure Qualification Records (PQRs), which were reviewed and validated under the auspicesof the Welding Research Council. This SWPS-N is not valid using conditions and variables outside the ranges listed.The American Welding Society and Naval Sea Systems Command (NAVSEA) consider that this SWPS-N presents informationfor producing an acceptable weld using the conditions and variables listed. This procedure is intended to be usedfor full penetration groove welds with consumable inserts. The user needs a significant knowledge of welding and acceptsfull responsibility for the performance of the weld and for providing the engineering capability, qualified personnel, andproper equipment to implement this SWPS-N.
