What holds the molten ball of tungsten in place at the tip of the electrode during DCEP welding?

To determine

The factor that holds the molten ball of tungsten in place at the tip of the electrode during DCEP welding.

Explanation

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.

DCEP welding: The DCEP (direct current electrode positive) process is also called reverse polarity. The heat concentration with DCEP welding is higher at the tip of the electrode. The electrode absorbs 2/3 of the heat generation, and the work absorbs <
