Introduction to GTAW / TIG Pipe Course Curriculum: 


Course Description: The GTAW course is designed to teach students about the GTAW process on pipe, proper techniques and electrode selection for welding pipe in various welding positions. Welding pipe in the horizontal position (2G), vertical (5G), and 45 degree angle (6G) positions. Setting up in a 2G, 5G, & 6G position to weld a root pass, hot pass, fill passes, and cap passes all using GTAW to meet ASME welding code.
