Multi-compond Rare-earth Tungsten electrode:  

Oxide addition: Multi-compound rare-earth

Dopant: 1.0-4.0%

Impurities: <0.05%

Electric work function: 2.45eV-3.10eV

Color: Dark blue

Characteristic: Compound rare earth tungsten electrode is doped with various of oxides, with excellent welding performance.

Application: Mainly as substitute for radioactive thoriated tungsten electrode and otherr tungsten electrodes.

Ceriated-Tungsten electrode:

Oxide addition: CeO2

Dopant: 1.8-2.2%

Impurities: <0.05%

Electric work function: 2.7eV-2.8eV

Color: Grey

Characteristic: Ceriated tungsten electrode, with easier arc ignition and low arc maintaining current under low current circumstances, is substituted for thoriated tungsten electrode, especially for DC welding.

Application: Applied for the welding of pipelines and small components, and discontinous welding.

Lanthanated-Tungsten electrode: 

Oxide addition: La2O3 / La2O3 / La2O3 

Dopant: 0.8-1.2% / 1.3-1.7% / 1.8-2.2%

Impurities: <0.05% / <0.05% / <0.05%

Electric work function: 2.8eV-3.2eV / 2.8eV-3.0eV / 2.6eV-2.7eV

Color: Black / Gold / Sky blue

Characteristic: Lanthanted tungsten electrode, which is similar to thoriated tungsten electrode with the characters of no-radioactive, excellent electric conductivitu and welding performance, high carrying capability, minimum ratio of burnt area, can be substituted for thoriated tungsten electrode, mainly used for DC welding. 

Application: Mainly substitute for radioactive thoriated tungsten electrode.

Others like tungsten electrode suitable for AC welding of aluminum, magnesium, or their alloys, the tungsten electrode for military industry and aerospace industry, for carbon steel, stainless steel, nickel alloy, etc.

***The thorium elements are radioactive, we propose the new multi-compound rare-earth as substitution. ***
