MIG or TIG? Choosing the Right One for the Right Job


MIG, TIG, Stick, MMA, GMAW, GTAW. With so many welding processes out there, it can get tricky figuring out which one to use for your project.


In this blog, we’ll be discussing the differences between the two most common processes, TIG and MIG, and detailing when to use them.


MIG

Metal Inert Gas welding, or MIG welding, uses a wire electrode on a spool that is fed through on a user selected speed.


The welding arc is generated by an electrical current that runs through the base metal and the wire, which then melts the wire and welds it to the base, creating a strong and aesthetically pleasing weld.


MIG welding is best used on metals such as:

  • Steel,

  • Stainless steel, and

  • Aluminium alloys.

MIG welding is the best choice for beginner welders as it affords the user better control when used on thinner metals, and provides a high quality, clean finish.


TIG

Also known as Tungsten Inert Gas welding, TIG welding is better suited to more experienced welders and gives the user a higher degree of control over the weld, but it is significantly slower than other processes.


TIG welding can be used on a wide variety of metals, including:

  • Steel,

  • Stainless steel,

  • Aluminium alloys,

  • Chromoly,

  • Copper

  • Brass,

  • Magnesium, and

  • Titanium.
