Product Overview & Specifications
Our tungsten electrodes are manufactured by powder metallurgy, high-temperature sintering and precision centerless grinding. Each batch is tested for purity, density and dimensional tolerance before dispatch, ensuring consistent welding performance and long service life.
Note: WT20 (thoriated) contains radioactive thorium dioxide — handle, store and dispose of per local regulations. For a non-radioactive alternative, WC20 (ceriated) or WL20 (lanthanated) are recommended.
Electrode Types & Color Code
Select the right tungsten alloy for your base material and current type. Color rings follow international coding for quick, error-free identification on the shop floor.
