MIG (Metal Inert Gas) welding also known as GMAW (gas metal arc welding) was developed in 1940’s for welding aluminum and other non-ferrous metals.
In MIG welding process electricity is used to melt and join pieces of metal together. It is also known as hot glue gun. MIG welding provides greater productivity because a welding operator doesn’t have to stop to change rods and brush the weld repeatedly. This process can be learnt easily and cleaning is not required. It can weld metals like stainless, mild steel and aluminum. It can weld in all positions. One major advantage of MIG welding is that metal can be welded much faster than traditional welding.
MIG welding is divided into two: Bare wire MIG and flux core welding. Bare wire mig can weld thin metals and can be cleaned soon. Flux core welding is mostly used outdoors and does not require a cylinder of mig welding gas or a flow meter.
