Course Description: This course includes the techniques used for oxyacetylene welding (OAW) in all positions (flat, vertical, horizontal and overhead) and uses a variety of freehand and automatic burning equipment on different metals.
Objectives
Upon successful completion of this course, the student should be able to:
- Demonstrate the proper use and set up of the OAW and oxy-fuel cutting(OFC) units in a safe manner.
- Demonstrate the proper use and set up of the plasma arc cutting (PAC) unit in a safe manner.
- Demonstrate the proper use of the air carbon arc cutting and gouging (CAC-A) unit in a safe manner.
- Demonstrate proper use of the OAW process in all positions.
- Demonstrate proper OAW on various joint details.
- Identify and use the American Welding Society (AWS) classification for the selection of the correct filler materials for the job.
