Standard Welding Procedure Specification (SWPS) for Gas Tungsten Arc Welding with Consumable Insert Root of Carbon Steel (M-1/P-1/S-1, Groups 1 or 2) to Austenitic Stainless Steel (M-8/P-8/S-8, Group 1), 1/16 through 1-1/2 inch Thick, IN309 and ER309(L), As-Welded Condition, Primarily Pipe Applicati
用碳钢(M-1/P-1/S-1 第1或2组)自耗镶块根部与奥氏体不锈钢(M-8/P-8/S-8 第1组)进行钨极气体保护焊的标准焊接工艺规范(SWPS) 1/16至1-1/2英寸厚 IN309和ER309(L) 焊态 主要用于管道应用
This standard contains the essential welding variables for welding carbon steel to austenitic stainless steel in the thickness range of 1/16 through 1-1/2 inch, using manual gas tungsten arc welding with consumable insert root. It cites the base metals and operating conditions necessary to make the weldment, the filler metal specifications, and the allowable joint designs for groove welds. This SWPS was developed primarily for pipe applications.
