We are supplier specialized in manufacturing TIG tungsten electrode in China. Tungsten electrodes are widely used for daily glass fusion, melting optical glass, warming material, glass fiber, rare-earth industry and other areas. The arc resistance of tungsten electrode is advantageous. Arc column has a high stability, small rate of electrodes loss. Under the high temperature generated by arc, the electrode loss of TIG welding is quite small, it is called tungsten electrode ablation. And it is a normal phenomenon.
Tungsten electrode can be used in TIG welding. Based on tungsten, we add around 0.3% to 5% rare earth elements by powder metal such as cerium, thorium, lanthanum, zirconium, yttrium etc. The tungsten alloy bar is made through pressing process. Its diameter is 0.25mm to 6.4mm. Standard length is 70 to 600mm. Tungsten zirconium electrode can be welded under the condition of alternating current. Tungsten thorium electrode is widely supplied for direct current welding field. Tungsten electrode has features of non-radiation, low melting rate, long welding life and good arc resistance. Therefore, tungsten cerium alloy is the most appropriate material for low electric current situation.
Tungsten ElectrodeTungsten electrode is widely used for daily glass smelting, melting optical glass, warm material, glass fiber, rare earth industry and other fields. Diameter of the tungsten electrode ranges from 0.25mm to 6.4mm. Commonest diameters respectively are 1.0mm, 1.6mm, 2.4mm and 3.2mm. Standard length ranges from 75mm to 600mm. We can produce tungsten electrode as customers’ drawing.
