The brief introduction of tungsten electrode
Tungsten electrode is made of a kind of material with high melting point, corrosion resistance, high density, good thermal conductivity and electrical conductivity. Tungsten electrodes are widely used in the welding. No matter what it is grinding, polishing and black, the final color of tungsten electrode is different, we can tell the difference. In the tungsten electrode, the more important thing is that their final color is different, the tungsten content is also different. When welding, we should choose the right tungsten electrode, so that the welding is easier, it is important to obtain high quality welding. Some of the important factors that make the right choices to be considered are the types of power (inverter or transformer), the welding material (steel, aluminum or stainless steel) and the thickness of the material.

The tungsten electrode plays an important role in the arc starting arc, arc stability and welding quality. The loss of the quality of tungsten electrode in the high temperature arc is referred to as the ablation of the tungsten electrode. In order to facilitate the discussion of the ablation mechanism of tungsten electrode, ablation can be divided into the ablation of the oxide and the ablation of tungsten.

The color of the tungsten electrode is different, so the difference can be distinguished. Their final color is different, the tungsten content is also different. Cerium tungsten electrode is gray, lanthanum tungsten electrode is black, golden, yellow and sky blue, thorium tungsten electrode is yellow, red and purple, zirconium tungsten electrode is brown and white, yttrium tungsten electrode is blue.
