MIG and TIG - Different Welds, Different Applications

Tuesday, October 18, 2016


snIf you are into welding, there’s a good chance that you have at least heard of the two major types of welding: MIG and TIG. But what are the differences between these two methods and what is each different approach used for? Here are a few important factors to keep in mind.


MIG stands for Metal Inert Gas. MIG welds tend to be simpler as the process basically involves using one gun to connect two pieces of material. It is easy to learn than TIG welding, and is much more commonly used for small projects, especially for the typical casual or hobbyist welder with smaller projects.

TIG or Tungsten Inert Gas welding is a slightly more complicated procedure, but it also usually produces much more attractive results and is more versatile than MIG welding. While MIG welds are easier to learn and master as a beginner, TIG welding is an excellent tool for those who have been involved with welding applications for a while.

On a technical basis, the primary difference between MIG and TIG welding is that MIG welding has a coil of wire that is fed through to the torch. During the process, this wire is melted to become the filler that forms the weld. TIG welding works differently, using a tungsten electrode to superheats the metals that will be welded. Then welding rods are dabbed to weld the metals together.


Both types of welds can be utilized on just about any kind of project. Typical applications of MIG welding include automotive repair, as well as many pipe joint welds and even significant projects such as the building of bridges. MIG is the popular choice for hobbyists and everyday use – quick, simple and convenient.

By contrast, TIG welding can do many of the same things, but tends to offer greater control than MIG welding, which also makes it appealing for trickier welds, such as welding along a curve or rounded objects. TIG is also a cleaner process than MIG, generally, which can result in a smoother, more attractive looking weld that is also stronger than a MIG weld.
