Course Description: This course includes oxyacetylene welding (OAW), oxyacetylene cutting (OFC-A) and shielded metal arc welding (SMAW) processes, in the flat and horizontal positions on various joint details. It will also include safety procedures, electrode identification, joint fit-up and alignment, base metal preparation, weld quality, beads and fillet welds, with focus on theory and practice. All welds will meet the American Welding Society (AWS) qualification standards.
Objectives
Upon successful completion of this course, the student should be able to:
- Safely operate the OAW unit for welding and cutting in the flat position.
- Safely operate the SMAW units to weld in the flat and horizontal positions.
- Safely operate the SMAW units on various joint fit-ups and alignment.
- Demonstrate proper welding process of groove welds (with backing and open) per qualification procedures set by the AWS.
- Demonstrate proper base metal, beads and fillet welds qualification procedures per requirements set by the AWS.
- Identify and use the AWS classification of electrodes in selecting the correct electrode for the job.
