Tungsten Welding Rod

Gas tungsten arc welding gtaw also known as tungsten inert gas tig welding is an arc welding process that uses a non consumable tungsten electrode to produce the weld the weld area and electrode is protected from oxidation or other atmospheric contamination by an inert shielding gas argon or helium and a filler metal is normally used though some welds known as autogenous welds or.

Tungsten welding rod.

There are various tungsten electrodes that you can use for the process but not all will. The tungsten electrode is a critical component in the process as it channels the current required to establish the arc. The process utilizes a non consumable tungsten electrode that relays current to the welding arc. Welding electrodes from grainger can help weld stainless steel mild steel and more.
