TIG (Tungsten Inert Gas) welding, also known as GTAW (Gas Tungsten Arc Welding), is a precise and versatile welding method used to join metals. TIG welding utilizes a non-consumable tungsten electrode to produce an electric arc that melts the base metal and filler rod (if used) to create the weld. The process is shielded by an inert gas, typically argon, which protects the weld from atmospheric contamination. TIG welding is valued for its exceptional control, enabling high-quality welds on thin materials and critical applications and for example for stainless steel welding. It is commonly employed in industries like aerospace, automotive, and fabrication, where precision, aesthetic appearance, and weld integrity are crucial.
