High-temperature Resistant WCu Welding Electrode
High-temperature Resistant WCu Welding Electrodes consist of composite metal materials mainly consisting of high-purity tungsten powder and copper powder. These materials undergo processes including isotatic pressing and high-temperature sintering. The result takes advantage of the high melting point and hardness of tungsten and the excellent ductility, thermal conductivity, and conductivity of copper. The composite materials, therefore, have high mechanical strength and low thermal expansion at high temperatures and exhibit excellent arc erosion resistance.
High-temperature Resistant WCu Welding Electrodes have the thermal and electrical conductivity and high-temperature resistance necessary in resistance welding for projection and butt welding of high-melting-point materials, especially stainless steel and nickel alloys. The characteristic of being sweat-cooling helps in maintaining welding zone temperature, which in turn provides controlled wear to the electrodes and better consistency. As a result, electrode service life and overall production efficiency are increased.
You can customize how these electrodes perform by changing the tungsten-copper ratio. The more tungsten there is, the greater the heat resistance is, but then the conductivity is lower. To attain the density and consistent structure needed for more challenging uses, such as parts for aerospace and electronics packaging, the manufacturing methods used are isostatic pressing and copper infusion.
