Tungsten Inert Gas (TIG) welding refers to Gas Tungsten Arc Welding (GTAW). TIG welding was introduced in the 1940s by a welder named Russell Meredith during his work at Northrop Aircraft Corporation in California, USA when he successfully joined aluminum and magnesium alloys through this technique. The TIG welding process uses a non-consumable tungsten electrode to produce a weld. TIG welding can achieve high precision and cleanest welding. The process requires an inert shield gas that can be either argon, helium, or a mixture of both. Mastering TIG welding is the most challenging and complex of the three commonly used welding methods. In this article, we will write reviews of Best TIG Welders for industries like fabrication, automotive, shipbuilding, aerospace, home hobbyists, and others.
