AWS B2.1-4-218 – 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

This standard contains the essential welding variables for chromium-molybdenum steel in the thickness range of 1/8through 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.
