1.Lanthanated tungsten electrode is normally applied in DC welding, also works well in AC welding 2. non-radiation high current

Lanthanated tungsten electrode

it has good welding performance without radiation hazard. its electric conductivity is close to WT20. 1. WL10, wl15, wl20 lanthanated tungsten electrode can be able to bear high current and have the lowest burn lost rate. it is popular tungsten electrodes in the circle of welding

2. diameter: 1.0-12mm

3. length: 150mm, 175mm

4. quality of surface: ground finish, polish finish

 Lanthanum -ungsten 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.
