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 electrodes 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 electrodes.

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. Electrodes 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.
