Standard Welding Procedure Specification (SWPS) forShielded Metal Arc Welding of Chromium-Molybdenum Steel (M-4/P-4, Group 1 or 2),
E8018-B2, 1/8 through 1/2 in. Thick, As-Welded Condition; 1/8 through 1-1/2 in. Thick,PWHT Condition, Primarily Pipe Applications
铬钼钢(M-4/P-4 第1组或第2组)屏蔽金属电弧焊的标准焊接工艺规范(SWPS)
E8018-B2 1/8至1/2英寸 厚 如焊接状态;1/8至1-1/2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 in. through 1-1/2 in. in the postweld heat treated (PWHT) condition,
using 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 standard welding procedure specification
(SWPS) was developed primarily for pipe applications.
