Welding is an important trade and is always in demand. Welding is needed in many trade areas and in many industries. Welding is used to permanently join pieces or parts of metal. Skilled welders can weld most metals using a variety of processes. The most common material for welding is steel. Steel is commonly welded by the use of a MIG welder (GMAW), stick welder (SMAW), or TIG welder (GTAW). In this activity plan students will learn and practise MIG, one of the easiest welding methods to learn.
