Lanthanated Tungsten Electrode:
Lanthanated tungsten electrode attracts close attention and becomes popular in international welding area for its unique welding performance; it is easy to use under AC or DC conditions; lanthanated electrodes operate at a slightly different arc voltage than thoriated or ceriated electrodes; developed around the same time as ceriated tungsten to help combat the increasing awareness of the radioactivity of thoriated tungsten; generally used to weld carbon and stainless steels, nickel alloys and titanium.
