New Materials For Tungsten-zirconium Electrodes

The main components of the tungsten-zirconium electrodes are tungsten (99%), zirconium oxide (0.7-0.9%), and other impurities. Under the same working conditions, the burning rate of Zr-Tg electrodes is lower than that of Ce-Tg and Th-Tg electrodes, the service life is longer, and the temperature of the electrodes is improved. In addition, when the thickness of the workpiece is increased and the seam is narrow, the quality of tungsten-zirconium welding and cutting is higher than that of Cerium-Tungsten and thorium-tungsten.In terms of production costs, zirconium tungsten is cheaper than pure zirconium electrodes and can be widely used in AC arcs. Zirconium Tungsten Material α The low dose of radiation reduces the damage to the human body and environmental pollution and creates conditions for automated production. However, existing zirconium-tungsten materials have some shortcomings, such as high brittleness and poor pressure processing performance.
