Why does some tungsten erosion occur?

To determine

The reason of the erosion of the some tungsten.

Explanation

GTA Welding: In the Gas tungsten arc welding (GTAW) process, a non-consumable electrode (tungsten) is used for the arc generation. The melting of the electrode does not take place in this process, although the melting of work takes place at the spot where the arc impacts its surface. An inert gas is used to provide needed arc characteristics.

Tungsten electrode- Tungsten electrode is used in TIG (Tungsten inert gas) welding as a welding electrode. Tungsten electrode is the desired electrode for TIG (Tungsten inert gas) welding, because the tungsten electrode has a low melting point, and it is a non-consumable electrode. The tungsten electrode can easily be alloyed with different types of metals. In the tungsten electrode, thorium oxide is added to increase the current carrying capacity and life of the tungsten electrode...
