Standard Welding Procedure Specification for Naval Applications (SWPS-N) for Gas Tungsten Arc Welding 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
1/8英寸[3 mm]至1-1/2英寸[38 mm]厚、MIL-3XX、焊态主要用于海军应用的奥氏体不锈钢(S-8)钨极气体保护焊的海军应用标准焊接工艺规范(SWPS-N)
This standard contains the essential welding variables for austenitic stainless steel in the thickness range of 1/8 inch
[3 mm] through 1-1/2 inch [38 mm], using manual gas tungsten arc welding. It cites the base metals and operating conditions
necessary to make the weldment, the filler metal specifications, and joint designs for groove and fillet welds. This
SWPS-N was developed primarily for naval applications that require performance to NAVSEA Technical Publication
S9074-AQ-GIB-010/248,Requirements for Welding and Brazing Procedure and Performance Qualification.
