The Lanthanum Tungsten Electrode (WL20) is a high-performance tungsten alloy electrode, primarily composed of tungsten and a small amount of lanthanum. It offers excellent arc stability and a long service life. The WL20 electrode is particularly suitable for high-precision welding processes such as TIG welding, where it can maintain a stable arc in high-temperature environments, delivering precise welding results. It is widely used in industries such as aerospace, automotive manufacturing, shipbuilding, and nuclear energy, making it one of the most…
