Standard Welding Procedure Specification (WPS) for Gas Tungsten Arc Welding of Chromium- Molybdenum Steel (M-4/P-4, Group 1 or 2), ER80S-B2, 1/8 through 1/2 in. Thick, As-Welded Condition, 1/8 through 3/4 in. Thick, PWHT Condition, Primarily Pipe Applications
ER80S-B2 1/8至1/2英寸铬钼钢(M-4/P-4 1或2组)的钨极气体保护焊标准焊接工艺规范(WPS) 厚度 焊接状态 1/8至3/4英寸 厚 焊后热处理条件 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 3/4 in. in the postweld heat treated (PWHT) condition, using manual gas tungsten 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.
