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.
