Tungsten Electrode

Tungsten  electrode is electrode made of material of tungsten, which has high melting  point, high corrosion resistance, high density，and good thermal and  electricity conductivity. Tungsten electrode is widely used in welding for its  properties.

Tungsten  electrode are ground or polished and black rod. Their end colors are so different that the can be differences to be tell apart.

What’s more, their end  colors are the marks to differ the content of tungsten in tungsten electrode.

Tungsten  electrode is used when arc welding with the Tungsten Inert gas (TIG) process  or when plasma welding. In both processes the electrode, arc and weld pool are  protected from atmospheric contamination by an inert gas. A tungsten electrode  is used because it can withstand very high temperatures with minimal melting or  erosion. electrode are made by powder metallurgy and are formed to size after  sintering.

When welded, selecting  the correct tungsten electrode  is important to getting high-quality welds and making  your welding easier. Some important factors to be considered in making the  right choice are type of power source (Inverter or transformer), material to be  welded (steel, aluminum or stainless steel) and the thickness of the material.
