tungsten electrode for resistance welding
Tungsten electrode has high melting point. It's good for high temperature strength, creep resistance, temperature electric and electron emission. Moreover, tungsten is low coefficient of expansion and the lowest metal vapor pressure. In generally, we adopt powder metallurgy to produce tungsten.
Tungsten electrode is used in welding, high voltage anode, cathode discharge and heat transfer devices.
HOSO Metal design the electrode especially for the resistance welding.
tungsten electrode selection:
| types | composition | characteristic |
| pure tungsten electrode | ≥99.95% tungsten | high temperature resistance |
| tungsten cerium electrodes | 2% Cerium oxide | A low electron work function, strong arcing ability, long service life |
| tungsten lanthanum electrode | 1-2% lanthanum oxide | low electron work function |
| tungsten thorium electrode | 2% thorium oxide | good thermal stability, radioactive |
| tungsten rhenium electrode | 5% or 26% rhenium | creep resistance capability |
| tungsten copper electrode | 10-60% copper | hardness and electrical conductivity good balance |
HOSO Metal can supply the finished tungsten parts according to customer's drawing
