tungsten insert electrode for copper wire spot welding

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.

 

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)

 

Tungsten insert copper shank spot welding electrode with no defect bonding technology:
