WT20 thoriated tungsten electrode
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.
