WZ8 Electrode Zirconium Tungsten Electrode
1. Description of WZ8 Electrode Zirconium Tungsten Electrode:
An electrode type called zirconium tungsten electrode was created to address the drawback of pure tungsten electrode, which is prone to melting and contamination of the workpiece when used in high-load welding. It is spherical to reduce tungsten penetration and has good corrosion resistance.
Zirconium tungsten electrodes contain a small amount of zirconium oxide (ZrO2). Zirconium tungsten electrodes often fall between pure tungsten electrodes and thoriated tungsten electrodes in terms of their welding properties. In AC welding, zirconium tungsten electrodes are the most commonly used, because they are easier to start arc than pure tungsten, and the arc beam is stable, and it can also prevent pollution very well, and the current carrying capacity is also good. The best non-radioactive tungsten electrode, in general, is zirconium tungsten electrode from the perspective of performance.
2. Basic Features of WZ8 Electrode Zirconium Tungsten Electrode:
| Model | Added Impurity | Impurity quantity% | Other Impurities% | Tungsten% | Electric discharged power | Color Code |
| WZ3 | ZrO2 | 0.2-0.4 | <0.20 | The rest | 2.5-3.0 | Brown |
| WZ8 | ZrO2 | 0.7-0.9 | <0.20 | The rest | 2.5-3.0 | White |
3. Features of WZ8 Electrode Zirconium Tungsten Electrode:
Like pure tungsten electrodes, zirconium tungsten electrodes can only be welded in an alternating current environment. zirconium Tungsten electrode has good welding performance in alternating current environment. Especially in the case of high load current, the superior performance of zirconium tungsten electrodes is irreplaceable by other electrodes.
During welding, the end of the zirconium tungsten electrode can be kept in a spherical shape to reduce the phenomenon of tungsten infiltration, and has good corrosion resistance. Due to the emergence of other alternative products, the demand for zirconium tungsten electrodes will tend to decrease. The main alternative is tungsten lanthanum electrodes.
4. Application of WZ8 Electrode Zirconium Tungsten Electrode:
Zirconium tungsten electrodes are also used for high-quality beam welding. Optimal applications requiring minimal tungsten contamination. For alternating current, zirconium tungsten electrodes are typically used; direct current is not advised. Magnesium-aluminum and its alloys are welded using arc current using zirconium tungsten electrodes.
The welding performance of zirconium tungsten electrode is located between pure tungsten electrode and thoriated tungsten electrode. It is a tungsten electrode product developed to improve the disadvantage that pure tungsten electrode is easy to melt and pollute the workpiece under high load welding conditions.
