Standard Welding Procedure Specification for Naval Applications (SWPS-N) for Gas Tungsten Arc Welding with Consumable Insert Root of Carbon Steel (S-1), 1/8 inch [3 mm] through 1-1/2 inch [38 mm] Thick, MIL-MS-1 and MIL-70S-2, in the As-Welded or PWHT Condition, Primarily Pipe for Naval Applications
海军应用标准焊接工艺规范(SWPS-N) 在焊态或焊后热处理条件下 使用1/8英寸[3毫米]至1-1/2英寸[38毫米]厚的碳钢(S-1)自耗镶块根部进行钨极气体保护焊 MIL-MS-1和MIL-70S-2 主要用于海军应用的管道
The data to support AWS B2.1-1-315:2018 for Naval Applications (SWPS-N) have been
derived from the above listed Procedure Qualification Records (PQRs), which were reviewed and validated under the
auspices of 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
information for producing an acceptable weld using the conditions and variables listed. This procedure is intended to be
used for full penetration groove welds with consumable inserts. The user needs a significant knowledge of welding and
accepts full responsibility for the performance of the weld and for providing the engineering capability, qualified personnel,
and proper equipment to implement this SWPS-N.
