Mig welding

Mig Welding (Metal Inert Gas Welding) or Mag Welding (Metal Active Gas Welding) welding is the most popular of the arc welding processes, this is mainly
because Mig Welding is fairly easy and versatile.
Mig Welding strikes an arc between a continuously fed Mig Welding filler wire and the workpiece, whilst protecting the welding arc from oxidisation by pouring a shielding gas over the weld pool. The choice of weld shielding gas will depend on the material being used and the quality required.
Pure Co2 Welding Gas is the cheapest gas to use when Mig Welding, but produces a fairly fierce welding arc with more spatter and a harder weld. Co2 is suitable for Mig Welding on welding jobs where quality is not important.
