B2.1-1-232:2020 STANDARD WELDING PROCEDURE SPECIFICATION (SWPS) FOR ARGON PLUS 25% CARBON DIOXIDE SHIELDED GAS METAL ARC WELDING (SHORT CIRCUITING TRANSFER MODE) FOLLOWED BY ARGON PLUS 25% CARBON DIOXIDE SHIELDED FLUX CORED ARC WELDING OF CARBON STEEL

Member Price: $237.00

Non-Member Price: $316.00

This standard 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 gas metal arc welding (short circuiting transfer mode) with 75% argon plus 25% carbon dioxide shielding for the root followed by flux cored arc welding with 75% argon plus 25% carbon dioxide shielding for the balance. 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 SWPS was developed primarily for pipe application ISBN Print: 978-1-64322-074-1 ISBN PDF: 978-1-64322-075-8
