resistance welding electrode

. A -- Bonding Area

We guarantee the complete seamless connection of tungsten and copper under vacuum environment. The bonding strength between the two materials is more than 130MPa, the bonding area ratio is close to 100%, which there is no hole in the cross section, and the service life is 5-10 times longer than the general bonding method


. B -- Stick

The stick is made of chrome copper or chrome zirconium copper, which has the work performance of high conductivity, high heat dissipation and fast cooling speed.


. C -- Electrode End

High quality pure W, Mo and their alloys are used as electrode ends. After deep densification treatment, the electrode has high density and uniform intemal structure.

-- Advantages of Bless' electrode
. No pores, holes, and gaps, and the connection strength is> 120Mpa
(Copper and copper alloys are integrated with tungsten and molybdenum refractory metals. NDB integrated connection technology )
. High density and uniform internal organization structure
(Each electrode end has been densified)
 Smoothness below Ra0.8, Stable welding joints
. High melting point up to 3410 ° C, and is resistant to collision resistance, abrasion and non-adhesion to the workpiece
 Further optimize high temperature stability and creep resistance to meet customer requirements.
(Tungsten and molybdenum electrodes are added with rare earth elements)
It has the advantages of high conductivity, high heat dissipation, high temperature stability. Unlike ordinary electrodes, our mosaic electrodes are integrated with NDB in a vacuum environment, which has stable conductivity and heat dissipation.
