Doped Tungsten Tungsten blank blank article or section by section rotation, stretching, polishing and other processing of the tungsten electrode has good anti arc erosion, pitting Bond and the ability and excellent welding performance, Easy arc starting, carrying capacity, in particular, cerium tungsten electrode, because of its excellent arc characteristics and arc current of smaller dimensions, in industrial production is widely used. The company pioneered the development of the 70s cerium tungsten electrodes, and obtained a U.S. patent (patent number) and the European patent (No. B1). The company currently produces cerium tungsten electrode products are electrodes, tungsten electrode ternary rare earth compound, pure tungsten electrodes, tungsten electrode lanthanum, zirconium and tungsten, yttrium and thorium tungsten electrode tungsten electrodes, various types of electrodes according to customer requirements specification processing.
