Zirconium tungsten electrodes are mainly suitable for alternating current argon arc welding (AC TIG) processes, especially for welding reactive light metals such as aluminum, magnesium and their alloys. Since the zirconium tungsten electrode head can naturally form a regular spherical shape under the action of AC arcing, it can provide a stable and uniform arc heat source, making the heat input during the welding process more concentrated and accurately controlled, thereby ensuring the quality of the weld. Aluminum and magnesium alloys have good thermal conductivity and easily oxidized surface properties, and the use of zirconium tungsten electrodes can effectively reduce arc instability and spatter, reducing welding defects.
Additionally, zirconium tungsten electrodes are widely used in industries such as aerospace, automobile manufacturing, shipbuilding, and food equipment for welding these metals to meet the needs of high-quality and high-precision welding. Although zirconium tungsten electrodes are not suitable for DC welding, they exhibit excellent performance and durability when welding aluminum and magnesium materials, making them an important electrode choice in this field.
