TYPICAL WELDING SKILL TRAINING CURRICULUM &

Schedule 60 carbon steel pipe welded in the Horizontal (2G) and Vertical/Overhead (5G) position, with backing rings, using the SMAW process with EXX18 low hydrogen electrodes. C. Course Objective:To enable the student to produce quality single vee groove welds on carbon steel pipe in all welding positions using a combination GTAW and SMAW process. WELDING OF STAINLESS STEELS AND OTHER JOINING In the fabrication of stainless steel products, components, or equipment, manufacturers employ welding as the principal joining method. Stainless steels are weldable materials, and a welded joint can provide optimum corrosion resistance, strength, and fabrication economy. However, designers should
