No-Ferrous metal Insert Spot welding Electrodes

No-Ferrous metal Insert Spot welding Electrodes


Tungsten electrode has high melting point. It has excellent proporites for high temperature strength, creep resistance, electron emission. Moreover, tungsten is low coefficient of expansion and the lowest metal vapor pressure. In generally, we adopt powder metallurgy to produce tungsten alloy.


Tungsten electrode is used in welding, high voltage anode, cathode discharge and heat transfer devices.

We use advanced CBT® technology bonding the shank with the No-ferrous metal tips. Which is no porosity issue between copper and tungsten. The electrode can acheive very good working life time and prodcution yeild rate. what is CBT technology?




HOSO Metal design the electrode especially for the resistance spot welding. For more details refer to our tungstent electrode catalogue. Normally, Our tungsten electrode has two types:

1: pure tungsten electrode

2: tungsten-faced electrode, shank material copper, BeCu, or CuCrlZr.

3: two kinds of join technology between tungsten and copper shank. Which is silver braze and NDB(No defect bonding)
