Standard Welding Procedure Specification (WPS) for Gas Tungsten Arc Welding (Consumable Insert Root) followed by Shielded Metal Arc Welding of Chromium-Molybdenum Steel(M-5A/P-5A), 1/8 through 1/2 in. Thick, As-Welded Condition, 1/8 through1-1/2 in. Thick, PWHT Condition, IN521,ER90S-B3, and E90E9018-B3,Primarily Pipe Applications Site License
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 through 1-1/2 in. in the postweld heat treated (PWHT) condition, using manual gas tungsten arc welding with a consumable insert root, followed by shielded metal arc welding. It cites the basemetals 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.
