Standard Welding Procedure Specification for Naval Applications (SWPS-N) for Shielded Metal Arc Welding of Carbon Steel (S-1), 1/8 inch [3 mm] through 1-1/2 inch [38 mm] Thick, MIL-7018-M, in the As-Welded or PWHT Condition, Primarily Pipe for Naval Applications
MIL-7018-M 厚度为1/8英寸[3 mm]至1-1/2英寸[38 mm]的碳钢(S-1)在焊态或焊后热处理条件下 主要用于海军应用的管道的保护金属极电弧焊的海军应用标准焊接工艺规范(SWPS-N)
This standard contains the essential welding variables for carbon steel in the thickness range of 1/8 inch [3 mm] through
1-1/2 inch [38 mm], using manual shielded metal 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 toNAVSEA Technical Publication S9074-AQ-GIB-
010/248, Requirements for Welding and Brazing Procedure and Performance Qualification.
