Tungsten Electrode

Tungsten electrode is a tungsten electrode made of materials with high melting
point, corrosion resistance, high density and good thermal and electrical
conductivity. Tungsten electrodes are widely used for welding in their
properties. Tungsten electrode grinding or polishing and black rod. The final
colors are different, which can distinguish the differences. In tungsten
electrodes, more importantly, their final color is different, and their
tungsten content is also different. When welding, select the correct tungsten
electrode to make welding easier. It is important to obtain high-quality
welding. Some important factors to consider in making the right choice are the
type of power supply (inverter or transformer), welding material (steel,
aluminum or stainless steel) and material thickness.

Applications:
Pure tungsten electrode is most widely used in AC welding; When pure tungsten
electrode is heated, the welding ball becomes sharp to provide a balanced
waveform AC welding, and the arc is stable; Pure tungsten electrode also
provides good arc stability for sine wave AC welding of aluminum and
magnesium.Click For More.
