Product Detail


high quality and purity temperature superfine spraying welding tungsten welding electrode


 high quality and purity temperature superfine spraying welding tungsten welding electrode


Tungsten electrode has excellent performance: small steam pressure, low resistance, good conductivity, small thermal expansion, high elastic modulus. Due to the characteristics of tungsten, it is very suitable for welding and electrode material. Such as in argon arc welding,   tungsten needle is used as the electrode of welding gun, striking the arc and stabilizing the  welding arc. In order to better exert its characteristics and improve the welding performance, add rare earth oxide in tungsten metal to stimulate its electron work function,to improve the welding performance: better arc striking and higher stability of the arc column,smaller burn out rate. Common rare earth additives are cerium oxide, lanthanum oxide, zirconium oxide, yttrium oxide and thorium oxide, etc.
