Tungsten Electrode

Attribute：
Tungsten electrode
It 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.

Product feature：

Tungsten electrodes feature an ultra-high melting point of approximately 3410°C, one of their most prominent advantages. This exceptional thermal property enables the electrodes to sustain stable physical and chemical characteristics under extreme high-temperature conditions, effectively resisting melting and thermal deformation. With superior arc heat resistance, tungsten electrodes deliver steady and dependable performance throughout welding and cutting operations.

The electrodes also exhibit excellent electrical and thermal conductivity. They facilitate efficient transmission of electric current and thermal energy, ensuring smooth and high-efficiency welding and cutting processes. Superior electrical conductivity minimizes energy loss, improves overall energy utilization, and stabilizes electric arcs consistently, which guarantees uniform and reliable welding quality.

Boasting high hardness and outstanding wear resistance, tungsten electrodes withstand frequent friction and contact during continuous operation. They resist abrasion and structural damage effectively, significantly extending service life and reducing frequent replacement costs.

Additionally, tungsten electrodes possess a low thermal expansion coefficient. They undergo minimal dimensional variation under drastic temperature fluctuations, maintaining precise structural integrity and dimensional stability. This property greatly reduces shape deviation caused by thermal expansion and contraction, ensuring long-term machining accuracy.

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.
