Product Detail

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
