Name:Lanthanated Tungsten Electrode WL15/20
Model:beiwu-4
Brief:The lanthanum tungsten electrode has excellent welding performance. The product is 1-2%La2O3 electrode added to tungsten. The electron escaping work is 2.7-2.8ev, which has the closest properties to the thorium tungsten electrode.When the medium and small current is used, the performance of the arc and the burning resistance are higher than that of the thorium tungsten electrode. Lanthanum tungsten electrode has become a promising substitute for thorium tungsten electrode because of no radioactivity. Another advantage of it is that the endurance current is high and the burning loss rate is the smallest. So lanthanum tungsten electrode is very popular with customers from Asia, Europe, America and Japan.
