Metal Inert Gas or MIG welding uses a continuously feeding wire, while Tungsten Inert Gas or TIG welding utilizes long welding rods and slowly feed them into a weld puddle. Both of them, however, use an electric arc to create the weld.
MIG welding is a simple and straightforward process that’s easier to learn compared to TIG welding.
MIG welders work by using an uninterrupted feeding spool of welding wire which burns, melts, and fuses the base as well as the parent metals together. They can weld a wide array of materials like aluminum, stainless steel, and mild steel.
Various materials with different thicknesses can be welded using MIG welding—from a thin gauge sheet of metal up to bulkier structural plates.
TIG welders, on the other hand, use the process for thinner gauge materials. Items made using TIG welding are stuff like tool boxes and kitchen sinks. The greatest advantage TIG welders can get from the process is that they can get their power down extremely low to avoid blowing through the metal.
TIG welding also allows welders to weld pipes and other heavier materials—they just need to own a unit that’s able to put out the amount of power they need.
When it comes to time, MIG welding is the quickest way to put down welds because of its use of a continuously feeding electrode. On the other hand, it’ll take a lot more time for TIG welders to finish the task because it requires a finer, delicate welding technique. I guess you can say TIG welding is more royal than MIG welding because of the intricate work that needs to be done.
The TIG welder is a more versatile machine because, with it, users can weld various types of metals—they’re just really slow. If you’re a beginner welder, however, it’s best to start with MIG welding before you proceed to the more precise TIG welding.
