MIG Welding and its Types
Metal Inert Gas in short term known as MIG welding. It is popularly known as Gas Metal Arc Welding. In Mig welding process the usage of aluminum alloy wire with the combination of filler material and electrode are used by the welders. The process is one of the easiest processes that one can learn to weld. As the welder is capable of meeting all the parameters of welds with the help of machine it can also be termed as semi-automatic weld.

Mig welding can be carried on at two different processes they are:

• Conventional Metal Inert Gas weld-
  In this process of welding it uses DC power source with constant voltage. As there is limitations for the spray transfer, for the arc current the welding has its lower limits. Since it is limited to certain range it can weld materials where the thickness being above 4 mm.
• Pulsed Metal Inert Gas weld-
  Here the passage of DC power source is retained at low and high intervals. When the welds are done at low current welders maintain the arc without transferring metals. And during the high current passage metals are transferred in spray mode. Therefore this makes Pulsed welding process to weld at high and low heat inputs which is not possible in conventional process. And the possibility of welding thinner materials is much easier at any positions.
