Zirconium tungsten electrodes are used for high quality welding of radiation, which cause the minimal tungsten contamination. Zirconium-tungsten electrodes are generally used for alternating current and are not recommended for direct current. Zirconium-tungsten electrodes are used for AC welding of magnesium-aluminum and its alloys.
The welding function of zirconium tungsten electrode is located between the pure tungsten electrode and the tantalum-tungsten electrode. It is a tungsten electrode product developed to improve the disadvantages of pure tungsten electrode which is easy to melt itself and contaminate the workpiece under high-load welding conditions.
The total consumption of tungsten electrodes in the world reaches 1600t per year, and the market demand is still growing with the development of the economy. The annual total output of tungsten electrodes in China accounts for about 3/4 of the world's tungsten electrode production. The annual output of tungsten electrodes in China has been growing steadily, and production has increased significantly since 2005, reaching 1200 tons in 2009.
The tungsten zirconium electrodes our factory produce is used well under alternating current and has good corrosion resistance. In welding, the ends can maintain a spherical shape and the arc is more stable than pure tungsten, especially at high load currents. Suitable for welding of magnesium, aluminum and their alloys under AC conditions.
