Lanthanated Tungsten Electrode (WL-10 / WL-15 / WL-20)
Lanthanated tungsten electrode has very good welding performance, what is more, the current conduction is most similar to thoriated tungsten electrodes but there is no radioactive pollution. So it is best product to replace thoriated tungsten electrode without any changes about welding operation process. Lanthanated tungsten electrode has become very popular as the surrogate product of thoriated tungsten electrodes in Europe and Japan. This tungsten electrode is very good used for D.C. or A.C. welding with superior welding performance. According to many internal reports and welding specialists’ experience, this electrode is the best surrogate products of thoriated tungsten electrodes and ceriated tungsten electrodes.
