How Hot is TIG Welding
TIG welding produces temperatures up to 35,000 degrees Fahrenheit, yet this concentrated heat can be precisely controlled and directed. When filler metal is required, it can be added manually by feeding welding rod into the puddle, similar to oxy-acetylene welding
What is TIG Welding
TIG stands for Tungsten Inert Gas and is technically called Gas Tungsten Arc Welding or GTAW. The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. The tungsten and weld puddle are protected and cooled with an inert gas, typically argon.
Why TIG Weld
TIG can be used to weld copper, titanium, even two dissimilar metals, and is handy for making tricky welds (e.g. s-curves, or welds on round things). TIG generates heat via an arc of electricity jumping from a (tungsten metal) electrode to the metal surfaces you intend to weld - usually aluminum or steel.
