Rwma Class 10 Facings And Inserts For Projection Welding Electrodes
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.
TUNGSTEN 55% – COPPER 45%, suited for facings and inserts for projection welding electrodes and flash and butt welding electrodes. It is recommended where (relatively) high electrical conductivity and some degree of malleability is desired.
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.
