Features pure tungsten electrodes and the characteristics of the thorium tungsten electrode tungsten welding electrodes

Pure tungsten high melting point and boiling point, evaporate easily melt and burn. However, tungsten electron emission capability than other poor, is not conducive to stable arc burning. Further, the current carrying capacity is low, poor anti-pollution performance. But the price is relatively cheap for magnesium in the exchange conditions. Welding of aluminum and its alloys. Thorium tungsten electrode excellent overall performance, strong electron-emitting ability, electron work function of 2.7eV, in particular, can withstand the overload current, stable arc, longer life expectancy, is the United States and some other countries, the most widely used tungsten electrode. But because there is a slight radioactive contamination, and its application is limited in some respects. Thorium tungsten electrode is usually made of carbon steel, stainless steel, DC welding nickel alloys and titanium. Huaye Tungsten and molybdenum focused on the development and production of tungsten electrodes, home and abroad by the unanimous recognition and praise, it is a trusted brand. Huaye Tungsten and molybdenum, look forward to working with you!
