TIG welding lanthanated tungsten electrode has no radioactive hazard, and has high durability current, minimum burnout rate, excellent welding performance, and the closest electrical conductivity to 2% thoriated tungsten electrode. Therefore, it is mainly used to replace the radioactively contaminated thoriated tungsten electrode.

You can count on these long-lasting lanthanated tungsten electrodes to perform TIG welding during your most difficult welding application, time and time again. With reliable arc-striking and a low burn-off rate, these electrodes maintain the highest quality of arc while adhering to ANSI and AWS standards. TIG welding lanthanated tungsten electrodes are popular due to the relative ease of striking an arc and lower amperage required. They perform exceptionally well in both AC & DC applications. And they are a good choice for welding titanium alloys, copper alloys, nickel alloys, and non-corrosive steels.
There are three grades of lanthanated tungsten electrode - WL10 (doping amount of lanthanum oxide is 0.8-1.2%), WL15 (doping amount of lanthanum oxide is 1.3-1.7%), and WL20 (doping amount of lanthanum oxide is 1.8-2.2%).
