What Is Mig And Tig Welding?

When it comes to welding, MIG and TIG are two of the most important welding processes. MIG, short for Metal Inert Gas and TIG for Tungsten Inert Gas are the two welding processes the majority of metal fabrication and welding is completed with these days, thanks to its accuracy, speed, and quality welds. In fact, around 80% of all welding that takes place today is done with either MIG or TIG welding.

And with the aid of modern welding technologies, the speed/efficiency of the process has increased significantly over the years, allowing users to complete larger welding projects quickly and efficiently.

MIG and TIG Welding Explained

Welding is a common process used to join two pieces of metal or plastic together. MIG and TIG welding are two types of welding processes used to bond metal alloys together at high temperatures, with MIG (Metal Inert Gas) welding being the most common form. The type of welding used will depend on the materials being welded and the end result desired.

MIG Welding

MIG welding uses a spool of shallow wire electrodes, usually steel alloy wire and gas to form the weld. These wires are fed into a handheld gun, which melts them and deposits them onto the workpiece.

When the weld is completed, the gas then flows out, shielding the heated zone from oxidation. MIG welding is used to build, repair and join projects involving thin and medium thicknesses. Advantages of MIG welding:

  • Easy to use
  • Can be automated
  • Quick welding process
  • Less expertise needed
  • Can weld thick and thin materials
Disadvantages of MIG welding:
  • Not suitable for outdoor welding
  • Susceptible to warpage and distortion
  • More expensive than welding with electrodes

TIG Welding

TIG (Tungsten Inert Gas) welding uses an arc to form the weld and is a slower process than MIG welding.

The ideal uses for TIG welding include thinner metals and materials. TIG welding requires more expertise than MIG welding, as the user must guide the torch that holds the tungsten electrode and the welding rod to form the weld.

The inert gas flows from the nozzle to protect and shield the weld from oxygen and nitrogen. Advantages of TIG welding:

  • Welding can be done in all positions
  • High quality weld
  • Can be used to weld a wide range of metals
  • Can be used for small detailed jobs
Disadvantages of TIG welding:
  • Not suitable for welding thicker material
  • Long welding time
  • More expertise needed
  • Costly
Both MIG and TIG welding are great methods to join metals together.

The type of welding chosen will depend on the material being welded and the end result desired. While MIG welding is quick and less expensive, TIG welding is more suited for smaller detailed jobs with thinner metals. It is important to understand the advantages and disadvantages of both processes before starting any welding project.

Conclusion: MIG and TIG welding are two commonly used methods in the welding industry to join metals together. Both are great for different types of welding applications and understanding the advantages and disadvantages of each method can help ensure that the welding job is completed correctly and efficiently.
