How to Weld – MIG Welding and TIG Welding

MIG Welding

This is a basic guide on how to weld using a metal inert gas (MIG) welder. MIG welding is the awesome process of using electricity to melt and join pieces of metal together. MIG welding is sometimes referred to as the “hot glue gun” of the welding world and is generally regarded as one of the easiest type of welding to learn.

TIG Welding

TIG Welding is one type of welding amongst a few choices you have – MIG, Stick, Oxyacetylene, etc.

TIG can be used to weld copper, titanium, even two dissimilar metals, and is handy for making tricky welds (e.g. s-curves, or welds on round things)..

TIG generates heat via an arc of electricity jumping from a (tungsten metal) electrode to the metal surfaces you intend to weld – usually aluminum or steel.

TIG stands for Tungsten Inert Gas, after the tungsten electrode, and the sheath of inert gas (argon or an argon mixture) surrounding it.
