Standard Welding Procedure Sspecification (WPS) for; Gas Tungsten Arc Welding of Carbon Steel (M-1/P-1/S-1, group 1 or 2), 1/8 through 1-1/2" think, ER70S-2, as-Welded or PWHT Ccondition (primarily pipe applications)
标准焊接工艺规范(WPS);碳钢的钨极气体保护焊(M-1/P-1/S-1 第1组或第2组) 1/8至1-1/2英寸 ER70S-2 焊前或焊后热处理条件(主要是管道应用)
AWS B2.1-1-207:2019 contains the essential welding variables for carbon steel in the thickness range of 1/8 inch [3 mm] through 1-1/2 inch [38 mm], 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 fillet and groove welds. This SWPS was developed primarily for pipe applications.
