Thoriated Tungsten Electrode

Zoom	Name: Thoriated Tungsten Electrode Name: 北京天鹏钨钼科技有限公司 Model: tpwm-102 Brief: Radioactive thorium-tungsten electrode can be mild, but have excellent welding performance, especially under the condition of high current low burning rate.

Details

      Thoriated tungsten electrode falls within traditional electrodes with superior welding performance. It is free of arc interruption, arc scattering, arc levitation and spattering in process of welding, and it is characterized by stable electric arc and high temperature resistance. The tungsten electrode head may scarcely become round, and its service life is relatively long. However, thoriated tungsten electrode is slightly radioactive, and its application is therefore restricted and resisted to a certain extent.
