MIG/MAG welding course

The Metal Inert Gas (MIG) or Metal Active Gas (MAG) welding is a semi-automated process, widely used in many sectors of industry, such as Fabrication, Structural, Shipbuilding, Railroad construction and production of heavy plants and machinery.

The process melts and fuses metals using the intense heat generated by an electric arc between the metals to be joined and a filler wire (solid or flux cored).  The wire is progressively melted at the same speed at which it is being fed by the wire feeder and forms part of the weld pool.  Both the arc and the weld pool are protected against atmospheric contamination by a shield of inert (non-reactive) gas
