Knowledge sharing of MIG welding

MIG Welding

MIG welding (Metal Inert Gas) or metal arc welding was originally developed for welding aluminium and other non-ferrous metals. It is usually an automatic or semi-automatic process whereby an electrode joins two pieces of metal as a direct current is continuously passed through a welding gun. This is done at the same time as an inert gas is also passed through the gun which stops any air borne contaminants entering the weld area--Sale Of Welding Positioner.

MIG welding allows the welding process to be much faster than other methods which makes it ideal for welding softer metals such as aluminium.

It produces continuous welds faster than traditional methods, and produces cleaner welds

As it is very versatile, MIG welding can be used with a wide variety of metals and alloys.

TIG Welding

Tungsten inert gas welding or TIG welding, for short, is an arc welding process that uses a tungsten electrode to produce the weld--Sale Of Welding Positioner.

Similar to MIG welding in that the weld area is also protected from atmospheric contamination via an inert gas (usually Helium or Argon or a combination), and a filler metal is often used, although certain welds, called autogenous welds, do not require this. The constant-current produces energy which in turn, is conducted across the arc through a combination of ionized gas and metal vapours which is known as plasma.

TIG Welding is often used to weld non-ferrous metals such as magnesium, copper alloys and aluminium and thin sections of stainless steel and as the technique gives the experienced welder greater control over the weld it has some advantages over MIG welding in that it can produce even higher quality and stronger welds--Sale Of Welding Positioner.

The filler rod is usually made from the same material as the base metal and is used for reinforcing joints and welding heavy metals.

Several joint types are used in TIG welding inclusive of butt joints (which do not always require the filler rod assistance), lap joints, corner joints and t-joints.

It is however, more complex than MIG welding and harder to learn and is much slower that most of the other techniques--Sale Of Welding Positioner.
