Inert Gas Welding, commonly known as Gas Tungsten Arc Welding (GTAW) or Tungsten Inert Gas (TIG) welding, involves using a non-consumable tungsten electrode to produce the weld, with an inert gas shield to protect the weld area from atmospheric contamination. This process is known for producing high-quality, precise welds on a variety of metals, including aluminum and stainless steel, making it ideal for applications requiring strong and aesthetically pleasing joints.
