Tungsten Inert Gas (TIG) Welding, also known as Gas Tungsten Arc Welding (GTAW), is a precise welding process that uses a non-consumable tungsten electrode to produce the weld, with an inert gas shield protecting the weld area from atmospheric contamination. This method is highly valued for its ability to produce high-quality, clean welds on a variety of metals, including aluminum and stainless steel, making it ideal for critical applications in industries like aerospace and automotive.
