Gas Tungsten Arc Welding (GTAW) is a welding process that uses a non-consumable tungsten electrode to produce the weld. An inert gas, typically argon or helium, shields the weld area from contamination, ensuring a clean and strong joint. This method is known for its precision and is often used for welding thin materials. GTAW is versatile and can be applied to various metals, including aluminum, stainless steel, and copper. It is commonly used in industries such as aerospace, automotive, and manufacturing, where high-quality welds are essential. The process requires skill and practice to master, making it suitable for both professional and hobbyist welders.
