Tungsten Inert Gas (TIG) welding is the process of melding together reactive metals like aluminum and magnesium. Since TIG welding utilizes an argon, helium, or argon-helium combination protective gas cloud (similar to MIG welding) at the tip of the welding nozzle, TIG welds are typically very clean with no oxidation. This protective gas cloud directly on the outside of the welding torch nozzle is fed by a tank of the tungsten inert gas through a cable and into the body of the welder. Though a TIG welder can be used on many different types of metals, aluminum and steel are the two most common types that people use it with.
TIG welding is a type of arc welding, meaning that it uses high voltage electricity to create enough heat to weld metal. There are multiple heat settings on TIG welders to get the most range and dynamic heat capabilities for different kinds of welds. TIG welding can take a long time to master, and it is not advised for beginner welding use. However, learning how to properly weld using a TIG welder can render the cleanest, smoothest and even strongest welds for any professional-grade automotive project.
