Course Description

Final course in a three-course sequence focused on introductory level skills used in structural plate welding in accordance to AWS D1.1 Structural Steel Welding code. Advancing to more difficult weld joints such as 1G and 2G V-groove butt joint on plate using the SMAW and GMAW process and destructive bend test. Perform outside corner joints in all positions. Introduces the GTAW process in 1F and 2F positions on mild steel and aluminum.
