Q:

What is the difference between MIG and TIG welding?

A:

Quick Answer

The difference between MIG and TIG welding is that the MIG welding technique feeds a continuous spool of wire into the melding puddle while TIG uses long welding rods to accomplish a similar task. The MIG welding process is done with metal inert gas. The TIG welding process is done with tungsten inert gas.

Full Answer

Both MIG and TIG welding techniques are widely used and require a certain amount of practice before they are mastered. Out of the two, MIG welding is easier to learn and perform. A MIG welder feeds a continuous spool of wire that melts after burning at a high temperature. Metals that work well with this technique include aluminum, steel and mild steel. MIG welding is very versatile and used on many different types of welding projects. MIG welding machines are recommended for less advanced projects.

TIG welding requires a bit more skill to master. TIG welding uses long metal rods of various sizes. Some common metals used with this method are aluminum, copper, stainless steel and iron. A rule of thumb is to use thin rods with thin metals and thick rods with thick metals. This form of welding is often used on projects requiring thin metal. TIG offers a lot of versatility when working on more intricate welding projects.
