The three most common welding types are – Arc, MIG and TIG welding. Let's take a closer look and discuss some similarities and differences between them. Arc welding also referred to as stick welding is the oldest of the three and probably the most cost efficient.

Plasma welding is an arc welding process that uses a plasma torch to join metals. The principle of this method is derived from GTAW aka TIG welding, where an electric arc is struck between the electrode and the workpiece.
