The Difference Between MIG and TIG Welding

When you start investigating the world of welding, one of the first things you may have questions about is MIG and TIG. While they sound alike, the practice of each type of welding and their tools, techniques, and applications differ. Ready to get your feet wet with some information about these methods?

INTRO TO MIG

The MIG in MIG welding stands for Metal Inert Gas. This type of welding is often a starting place for folks getting into the industry. But don’t be deceived; that doesn’t mean MIG welding is for beginners only. This method is achieved by using a wire-fed gun with the reel located within your welding machine. When you pull the trigger to weld, wire moves out of the tip of your gun at a rate of your choose and works as both the electrode to ignite the arc and as the filler to fuse the metals you’re working with. Because of this dual action, MIG welding is very effective for thicker welds, making it a universally used technique.

INTRO TO TIG

On the other hand, there’s TIG welding, which stands for Tungsten Inert Gas. In this method, a filler rod is held with one hand while the welding gun is held with the other. Where MIG welding supplies the wire through the machine, in TIG, you provide the filler with the rod in your other hand. TIG has the advantage in being able to be used for a more diverse pool of metals, but MIG is often chosen instead because of increased speed and ability to work with thicker materials.
