Method of connecting workpieces using capacitor discharge welding involves forming weld via high impulse discharge and pressure

摘要

The method of welding workpieces together involves connecting the workpieces by applying a high impulse current and pressure to fuse the work material. The pressure is increased around the time of the high current discharge and prior to a secondary high current discharge. The electrode can be moved closer during the second high impulse discharge, or for each discharge.
