Course Description

All arc welding processes use an arc to complete a circuit and provide heat for the melting of materials. However, arc welding processes differ in how the arc is produced and controlled, how the molten weld pool is protected from oxidation, and whether it uses a consumable or nonconsumable electrode. In this module, we focus on the process of plasma arc welding.
