WPS Indosol 001 (ASME) R

This welding procedure specification outlines the requirements for welding single V-groove joints between 1.5-14.2mm thick SA 106 Gr. B and SA 108 Gr. B steel plates using gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW) in all positions. The root pass will be completed with GTAW using an ER 70 S-G 2.4mm diameter filler metal, followed by GTAW and SMAW hot passes and fill passes using ER 70 S-G and E 7018 3.2mm diameter filler metals. A SMAW cap pass will complete the weld, with all passes deposited at 80-150 amps and 20-
