Resistance Welding Electrodes Bonded by Back-casting
Back-cast materials simultaneously combine the material properties of two different material components. During this process, the materials themselves are retained in their original state and are bound only at a thin junction. The metals are fused in a mould to form a bond of only a few micrometres in size. Unlike welding and soldering techniques, this method is particularly stable and ensures optimum thermal conduction.
The tungsten-plated electrode uses tungsten as the electrode end, and the rod portion is made of copper or chrome-zirconium copper to maintain high conductivity and high heat dissipation.
Weilai is a professional manufacturer of tungsten-copper joints, the resistance welding electrodes we produce also called combined electrode, high-quality tungsten alloy is used as the electrode end, and the internal structure is dense and free of voids. The rod is made of copper or chrome-zirconium copper, which maintains high electrical conductivity and high heat dissipation.
Production process: blanking → back casting → machining → polishing → inspection → packaging
