MIG Welding
MIG Welding is an arc welding process wherein coalescence is produced by heating the job with an electric arc established between a continuously fed metal electrode and the job.
No flux is used but the arc and molten metal are shielded by an inert gas, which may be argon helium is CO.
Before igniting the arc, gas and water flow are checked. Proper current and wire Fedwire-feed speed is set and electric connections are ensured. Mig welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join 2 pics of metal as it continuously feeds through a welding gun. The inert gas acts as a shield, keeping air-born contaminants away from the weld zone. The arc is produced between the electrode and continuously feeds metal wire real which melts for continuous welding process for large-size welding w/p.
