WLa 10/15/20 Lanthanated-Tungsten Electrode
Lanthanum tungsten electrodes have excellent welding performace, and their arc performace and burn resistance are impoved compared to thorium tungsten electrodes when used at low and medium currents. Lanthanum tungsten electrodes have high durability and minimal burn out rate.
Application: stainless steels, carbon steel, Nickel, Titanium, Copper, Magnesium, Aluminium and its alloys..
