WL20  Lanthanum Tungsten electrodes   TIG welding  WL Tungsten electrodes 

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.

Features:

1. Pure tungsten, the least expensive of all tungsten, is generally used in the AC welding of Al & Mg and it's alloy

2. Yttrium-tungsten is primarily used in military and aviation industry with narrow arc beam, high compressing strength, highest welding penetration at medium and high current

3. Cerium- tungsten is a non-radioactive material, popular to be used for welding tube, pipe, very small parts, short welding cycles.

4. Thorium- tungsten is a low-radioactive material, mainly used for DC welding of carbon, SS, nickel alloy and titanium, etc.

5. Lanthanum- tungsten is a non-radioactive material, mainly used for DC welding but also show good results for AC welding.

6. Zirconium tungsten is most commonly used for AC welding of Al & Mg and it's alloy.
