Standard Welding Procedure Specification (SWPS) for Gas Tungsten Arc Welding of Chromium-Molybdenum Steel (M-5A/P-5A), ER90S-B3, 1/8 through 1/2 in. Thick, As-Welded Condition;1/8 through 3/4 in. Thick, PWHT Condition, Primarily Pipe Applications
ER90S-B3 1/8至1/2英寸铬钼钢(M-5A/P-5A)的钨极气体保护焊标准焊接工艺规范(SWPS) 厚 如焊接状态;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 standard welding procedure specification
(SWPS) was developed primarily for pipe applications.
