Brief：Thorium-tungsten electrode is one of the first use of rare earth tungsten electrodes, welding performance is so far the best variety of tungsten electrodes, therefore, at a global scale of the variety of tungsten electrodes the highest market share, but because thorium tungsten electrode in powder metallurgy and cast rolling mill the process of radioactive pollution will happen, so Europe and the United States to limit the production of the varieties of electrodes, but because of its excellent welding performance, its use has not been restricted.

　Thoriated Tungsten

Thorium-tungsten electrode is one of the first use of rare earth tungsten electrodes, welding performance is so far the best variety of tungsten electrodes, therefore, at a global scale of the variety of tungsten electrodes the highest market share, but because thorium tungsten electrode in powder metallurgy and cast rolling mill the process of radioactive pollution will happen, so Europe and the United States to limit the production of the varieties of electrodes, but because of its excellent welding performance, its use has not been restricted.
