What’s the difference between Mig and Tig Welding?



What is MIG Welding? 

Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.


What is TIG Welding?

Gas tungsten arc welding, also known as tungsten inert gas welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.


Which is better?

Generally speaking, MIG welding is more often recommended for ease of use. The process tends to be a bit more forgiving of mistakes than TIG welding is so it’s often recommended for first-time operators and non-professionals. The answer depends on the job in question. As noted earlier, MIG welding is typically better for heavy-duty welding work where larger, thicker pieces of metal are being joined because it uses filler material.

However, TIG welding can work wonders for joining smaller pieces of metal, such as the wires for a custom steel wire basket. Also, because the TIG process directly joins two pieces of metal, there’s no filler material to fail.

With robotic welding equipment, TIG welding can be a bit lower-maintenance, since the welding electrode isn’t being constantly consumed by the welding process. However, the welding electrode still needs to be properly cleaned and polished between uses especially when welding stainless steel.
