TIG	MIG
TIG stands for Tungsten Inert Gas Welding	MIG Stands for Metal Inert Gas Welding
It uses non consumable tungsten electrode rod with an inert gas	It uses a consumable wire connected to an electrode current
The thickness of plates that can be welded using TIG is limited. Usually, thin gauge materials can be welded.	MIG can be applied to weld a range of material thicknesses.
TIG is comparatively slow welding technique.	MIG as compared to TIG is relatively faster due to continuously fed electrode
TIG welding needs a relatively skilled workers	MIG requires relatively less skilled workers
TIG is a fine and delicate welding technique	MIG is a fast way of putting down the welds.
TIG is used mostly for joining of non ferrous metal and	MIG is used for welding of variety of materials such as stainless steel, mild steel and aluminium.
Weld is considerably cleaner due to the use of tungsten electrode, since it produces less contamination	Chance of weld contamination is high
Tighter tolerances need to be maintained	Tolerance levels need not be so high
The process can be semi automatic or manual	The process can be automatic or semi-automatic

ADD COMMENT EDIT

Hi Juilee - I really like the breakdown of explaining the differences! Just one thing I'd add is how the type of gas affects the weld. If I use Co2 for MIG welding the quality is nowhere near TIG welding, but when I use Co2 & Argon mix, the quality is actually a lot closer to a TIG Argon weld. This, combined with the speed of the weld (as you stated) is why I usually prefer MIG welding. If anyone wants any more info about this, this guide should help.
