Tungsten rods are the best choice for high temperature environments. No metal in nature can withstand higher temperatures than tungsten. It has a melting point of 3410°C, and at high temperatures pure tungsten retains extremely high tensile strength.

Tungsten rod is a tungsten electrode made of materials with high melting point, corrosion resistance, high density and good thermal and electrical conductivity. Accurate grinding of tungsten electrode is an important condition for argon arc welding and high quality plasma welding.

Tungsten electrode rod is widely used in welding industry because of its excellent performance. Tungsten rod grinding or polishing and black rod. The final colors are all different, so you can tell the difference. In tungsten electrodes, more importantly, they have different final colors and different tungsten content. When welding, it is important to choose the right tungsten electrode to make welding easier and 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 type of material thickness. Tungsten electrode plays an important role in arc initiation, arc stability and welding quality in argon tungsten arc welding. The mass loss of tungsten electrode under the action of high temperature arc is called tungsten ablation. In order to discuss the ablative mechanism of tungsten electrode, the ablative mechanism can be divided into oxide ablative and tungsten ablative.
