Resistance Welding

Resistance Welding is the process of welding two pieces of material together by passing a high voltage current through a localised area, causing them to melt and fuse together.

A positive and negative electrode pinches the two pieces of material together. A high voltage discharge is then passed between the respective electrodes, the high voltage causes both materials to plasticise, the clamping force, ensures the two material’s fuse together.

An individual weld or a number of welds can be performed simultaneously because the size of the electrodes does not drive the size and shape of the weld, the main driver is that the voltage can be specifically directed.
