Zirconium Tungsten Electrode

Brief Introduction

Under alternating current, Zirconium Tungsten performs good and has good corrosion resistance. In welding, the ends can maintain a spherical shape and zirconium tungsten electrode is more stable than pure tungsten, especially at high load currents. It is suitable for welding of magnesium, aluminum and their alloys under AC conditions.

The tungsten electrode is a kind of electrode developed to improve the disadvantage that the pure tungsten electrode is easy to melt and contaminate the workpiece under high-load welding conditions. The biggest characteristic of the electrode is that the end of the electrode can be maintained under the condition of high load current. It has a spherical shape to reduce tungsten penetration and has good corrosion resistance.

The zirconium tungsten electrode contains a small amount of zirconium oxide (ZrO2). The soldering characteristics of the zirconium-tungsten electrode are generally located between the pure tungsten electrode and the tantalum tungsten electrode. In AC welding, zirconium-tungsten electrode is the most commonly used because it is easier to arc than pure tungsten during welding, and the arc beam is stable, and it can also prevent pollution, and the current carrying capacity is also good, from the performance point of view. In general, zirconium tungsten electrodes are the best non-radioactive tungsten electrodes.

Characteristics of zirconium tungsten electrode

Tungsten zirconium electrodes, like pure tungsten electrodes, can only be soldered in an AC environment. The tungsten-zirconium electrode has good welding performance under AC environment. Especially in the case of high load current, the superior performance of the tungsten-zirconium electrode is irreplaceable for other electrodes.

During welding, the ends of the tungsten zirconium electrode can be kept in a spherical shape to reduce the phenomenon of tungsten penetration and have good corrosion resistance. Due to the emergence of other alternative products, the demand for tungsten zirconium electrodes will decrease. The main alternative is the tungsten rhenium electrode.
