MIG welding was developed in the 1940's and these initial general principles have stayed very much the same throughout this time. An arc of electricity is used in MIG welding, this is to create a short circuit between the continuously fed anode, which is the wire-fed welding gun, and a cathode, the metal being welded.
The heat produced by the short circuit, along with a non-reactive inert gas melts the metal and allows them to mix together. The metal begins to cool and solidify once the heat is removed, and forms a new piece of fused metal.
MIG welding is able to be used to weld many different types of metals, these being: aluminium, copper, steel, stainless steel, magnesium, nickel, as well as other alloys.
At MAS we can offer MIG welding machines, new, used machines, or for hire. And all the associated materials necessary.
