Standard Welding Procedure Specification (SWPS) for Gas Tungsten Arc Welding followed by Shielded Metal Arc Welding of Chromium-Molybdenum Steel (M-5A/P-5A), 1/8 through 1/2 in. Thick, As-Welded Condition; 1/8 through 1-1/2 in. Thick, PWHT Condition, ER90S-B3 and E9018-B3, Primarily Pipe Applic
1/8至1/2英寸铬钼钢(M-5A/P-5A)的气体保护钨极电弧焊后的标准焊接工艺规范(SWPS) 厚 如焊接状态;1/8至1-1/2英寸 厚度 焊后热处理条件 ER90S-B3和E9018-B3 主要用于管道应用
This standard contains the essential welding variables for chromium-molybdenum steel in the thickness range of 1/8
through 1/2 in. in the as-welded condition; or 1/8 through 1-1/2 in. in the postweld heat treated (PWHT) condition, using
manual gas tungsten arc welding followed by manual shielded arc welding. 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 standard welding procedure specification (SWPS) was developed primarily for pipe applications.
