MIG vs TIG Welding - Which One Is Better?

Before deciding which welding method is best for you, check out our Blog Post below for the things you will need to consider first.

Welding, put simply is the fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. In the Welding world, there are two common types of welding, MIG (Metal Insert Gas) Welding and TIG (Tungsten Insert Gas) Welding, and while they have some similarities, they are vastly different. MIG welding uses a solid wire that is machine-fed to the weld area while TIG uses a non-consumable electrode and a hand held filler rod to form the weld. Both methods both use an electric arc and shielding gas to join different metals,but knowing the kinds of products that TIG and MIG welds are suited for can lead you to a decision about which weld type you may prefer on your next project. Things you may need to consider before deciding on which welding technique is best for you:

  • Material Thickness - The precision and accuracy of TIG welding means that it is ideal for joining thin materials that may be susceptible to burn through or warping, where as MIG welding is suitable to use on a variety thicker metals.

  • Length of runs – TIG welding is best suited to short runs, while the continuous wire feed of MIG welding means it is is better suited to higher levels of productivity as the welder doesn't need to stop and start as often. MIG welding is also a lot faster than TIG welding so larger runs simply don't take as long to complete.

  • Aesthetics – TIG welding is the option to go for when the look of the final look of the weld is important. Visible pieces will look better with TIG welding, as it allows for a more precise weld

  • The Welders Experience – Most welders start out learning how to MIG weld, and as they gain experience then progress onto TIG welding, the more complex of the two. All of the above benefits of TIG welding to lean on the fact that you have an experienced welder working on your projects.

MIG welding is generally better suited for joining thicker metals, and for jobs that require high levels of productivity. It is also a faster process than TIG welding, and requires little to no cleaning and finishing once complete, resulting in short lead times and lower production costs for the business. Additionally it is easier to learn and only requires the use of one hand, assisting the welder in balancing and holding other pieces. However it's welds are not as precise, strong or clean as those formed by TIG welding operations.

So, which is better, MIG or TIG Welding?
