Prerequisites with concurrency
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.
1. Demonstrate safe practices in the MATC Welding Lab.
2. Weld common (basic) outside corner and groove assemblies with SMAW and GMAW processes to AWS D1.1 Structural Steel Welding Code.
3. Demonstrate appropriate set up, maintenance, and use of GTAW equipment for basic weldments.
4. Weld common (basic) joint assemblies with GTAW processes to AWS D1.1 Structural Steel Welding Code.
5. Demonstrate appropriate set up, maintenance, and use of FCAW equipment for basic weldments.
6. Apply visual and destructive examination principles and practices in accordance with AWS D1.1 W.
