Tungsten And Molybdenum Electrodes For Resistance Welding, Spot Welding
Description:
For resistance welding, the parts will be pressed and heated under high current until the parts are joined together.
And for welding, the force between the electrode and the parts are large. Some of them can reach to 450 MPa.
Uncer this process, it rises great challenge for the welding electrodes.
The Tungsten - Copper combination produces dense, hard metals of superior wear resistance and strength at elevated temperatures. In addition,
By brazing tungsten with copper, the electrode can have the property of superior wear resistance and strength under high temperatures.
And hey possess good thermal and electrical conductivity.
They are suited for Suited for projection welding electrodes, electro-forming and electro-forging electrodes facings for upsetting of studs and rivets, cross-wire welding of large diameter wire and rod, flash and butt welding electrodes, spot welding electrodes, light upsetting and seam welding bushings. Harder than Class 10 and used where moderate pressure is required.
For joint method between shaft and our refractory metal, we can offer braze welding and also back casting.
Our products can be used for spot welding, projection welding and also thermode welding.
