Welding

Welding is a joining process that permanently joins together two separate components with heat, pressure, or a combination of both to make one new part. Welding is one of the most economical ways to join two metals permanently. Arc welding uses the power of electricity to generate the heat necessary to melt and join metals together.
These classes cover the basic components and common processes used during arc welding. They also provide an overview of the various types of welded joints and describe how electrical variables affect arc welding. Intermediate-level classes focus on the weldability of numerous metals and address the specific details necessary to begin hands-on training for the major arc welding processes.
