Zirconium Tungsten Welding Electrodes Description

Zirconium Tungsten Welding Electrodes contain a small amount of zirconium oxide (ZrO2). The welding characteristics of zirconium tungsten electrodes are generally between pure tungsten electrodes and thoriated tungsten electrodes. In AC welding, zirconium-tungsten electrode is easier to start arc than pure tungsten electrode, and the arc beam is stable, which is the most commonly used electrode. It also prevents pollution and has good current carrying capacity. In terms of performance, zirconium-tungsten electrodes are generally the best non-radioactive tungsten electrodes.

What is tungsten electrode?

Due to the characteristics of tungsten, it is very suitable for TIG welding and other electrode materials similar to this kind of work. Adding rare earth oxides to metal tungsten to stimulate its electronic work function, so that the welding performance of tungsten electrodes can be improved: the arc starting performance of the electrode is better, the stability of the arc column is higher, and the electrode burn rate is smaller. Common rare earth additives include cerium oxide, lanthanum oxide, zirconium oxide, yttrium oxide, and thorium oxide.
