This course presents new challenges from the first two courses. Students expand their knowledge and skills to perform and practice basic pipe welding techniques using two welding processes (SMAW & GTAW). The GTAW process is introduced and students practice performing basic root welds on pipe coupons. The remainder of the welding procedure applies SMAW processes to complete the fill and cap welds.

Reading and interpreting basic pipe drawings, students cut pipe coupons to length and bevel the pipe ends using thermal and mechanical beveling processes. Students face their first experience at practicing uphill and other welding techniques simultaneously. They practice welding in multiple positions as they travel around the pipe to complete the weld. Also, as a continuation of basic metallurgy, students learn various techniques for identifying types of metal using visual and mechanical testing techniques.
