Standard Welding Procedure Specification (WPS) for Gas Tungsten Arc Welding followed by Shielded Metal Arc Welding of Chromium-Molybdenum Steel (M-4/P-4, Group 1 or 2), 1/8 through 1/2 in. Thick, As-Welded Condition, As-Welded Condition, 1/8 through 1-1/2 in. Thick, PWHT Condition, ER80S-B2 and E801
1/8至1/2英寸铬钼钢(M-4/P-4 第1组或第2组)的气体保护钨极电弧焊后的标准焊接工艺规范(WPS) 厚度 焊接状态 焊接状态 1/8至1-1/2英寸 厚度 焊后热处理条件 ER80S-B2和E801
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 in. through 1-1/2 in. in the postweld heat treated (PWHT) condition, using manual gas tungsten arc welding followed by manual shielded metal 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 welding procedure specification (WPS) was developed primarily for pipe applications.
