Description: Focus on the Submerged Arc Welding process,(SAW), including the types and uses of automated welding processes. Topics to be covered are: electrical characteristics and power supplies, set up and operation of a single wire submerged arc welding system, basic troubleshooting, and weld quality evaluation. Students will interpret and develop weld procedure specifications/performance qualification records for the SAW process.

Prerequisites: None

Corequisites: None

Recommendations: A fundamental knowledge of welding processes.
