Zirconium-Tungsten Electrode bears a fine performance in welding under the condition of AC and has a good other electroe welding welding,the end of zirconium-tungsten electrode remains pellet-shaped which can reduce the possibility of tungsten oozing.It is suitable for welding magnesium,aluninum and their alloy under alternating current.
Compared with pure tungsten materials, thoriated tungsten has the following characteristics:
Lower electronic function; higher crystallization temperature ; better electrical conductivity ; good mechanical cutting performance.
Thorium tungsten electrode is a commonly used tungsten electrode material, which has superior welding properties than pure tungsten, so it is widely used in the field of direct current welding.
Thorium tungsten electrode is easy to operate and can work well even under overload current.
