Resistance welding

Resistance welding is a welding process for electrically conductive materials based on the Joule heating of an electrical current flowing through the connection point. This heats up the connecting parts until they fuse. A welded joint results after the current flow and the re-solidification of the melt. By pressing the parts together during and after the current flow, resistance pressure welding supports the formation of a deep connection.
