The weld area is protected from atmospheric contamination by an inert shielding gas, typically argon or helium. Advantages of Tig Welding Tig welding offers precise control over the welding arc, resulting in high-quality welds with minimal splatter and cleanup. It is suitable for welding thin materials and exotic metals like stainless steel, aluminum, and copper alloys. Applications of Tig Welding Tig welding finds applications in industries such as aerospace, Tig Mig Welder automotive, and art fabrication where high precision and aesthetics are crucial. Understanding Mig Welding What is Mig Welding? Mig welding, or Gas Metal Arc Welding (GMAW), uses a consumable wire electrode fed through a welding gun, along with a shielding gas, typically a mix of argon and carbon dioxide.
