4. Course Description:

This course covers the use of oxyfuel equipment while welding, cutting, brazing, and using the Plasma Arc Cutting (PAC) and Air Carbon Arc Cutting (CAC-A) processes. There will also be an introduction to laser cutting equipment. Time will be spent discussing safety while developing skills using thermal welding and cutting processes. Welding and brazing will be performed in the flat and horizontal positions. All cutting will be performed in the flat position. Written and fundamental tests will be completed in accordance with American Welding Society (AWS) codes and standards.
