Lanthanum -Tungsten Electrode is well known for its good welding performance .It is the electrode added with 1-2% of La2O3.The
power of its electronic transgression is 2.7-2.8ev ,bearing the
closest features to those of the Thorium - Tungsten Electrode. Its arc
features and burn spoilage endurance used with small and medium
currents.
Lanthanum-Tungsten Electrode is the substitution product of
thorium-tungsten electrode because of its non-radiation. Its other
advantage is its endurance of high current and low burn spoilage rate.
