There are many factors, which can influence the welding effort of resistance welding, which is applied tungsten copper as electrodes, such as welding current, time, pressure, electrode shape and properties and workpiece surface condition.

In the conventional method to produce nanoscaled WC–Co material, tungsten powder is obtained from the reduction of tungsten oxides or ammonium paratungstate (APT) followed by a carburization step to obtain tungsten carbide powder. Generally, the particle size of WC–Co powder is on the micron scale. Recently, solution chemical synthesis methods such as spray conversion process and chemical co-precipitation have received increased attention for the production of nanostructured WC–Co material in order to improve the properties of sintered WC–Co materials.

There are four types of resistance welding, which can use tungsten copper bonded copper electrode as welding tip, spot welding, seam welding, butt welding and projection welding.

Tungsten is one of the most highly refractory metals and is well applied in lamp filaments, heating elements in high temperature furnaces, electronic heaters, X-ray emission tubes, TIG welding electrodes etc. The widely applications of tungsten result from its thermal resistance to high temperature, high hardness, and high wear resistance.
