China WC20 2% Cerium tungsten tig electrode rod grey Manufacturer and Supplier

WC20 2% Cerium tungsten tig electrode rod grey

Short Description:

WC20 2% Cerium Tungsten Arc Welding Electrode is a tungsten electrode used in Tungsten Inert Gas Welding (TIG). Adding 2% cerium to the tungsten electrode improves its performance, especially in terms of arc starting and stability. The gray color of the electrode rod is usually caused by the cerium content.

Product Descriptions

Cerium tungsten electrode is a type of tungsten electrode product made by adding rare earth cerium oxide to a tungsten base through powder metallurgy and rolling, grinding, and polishing processes. It is one of the earliest non radioactive tungsten electrode products produced in China, known for its excellent arc initiation performance and stability under low current conditions.

Applications

Under low current DC conditions or electrode diameters below 2.0mm, cerium tungsten electrodes are the preferred alternative to thorium tungsten electrodes. In addition, cerium tungsten electrodes are also used in plasma cutting, plasma spraying, and plasma melting, replacing thorium tungsten electrodes. In electro-optic sources, cerium tungsten electrodes have been used for small and medium power xenon lamps. In electro-optic environments, cerium tungsten materials serve as sealing components and have good performance.
