ABSTRACT OF THE DISCLOSURE Portable friction welding apparatus comprises a drive motor for causing relative rotation between a pair of workpieces. An auxiliary energy store such as the flywheel is mounted coaxially to a drive shaft of the drive motor. The two workpieces may be urged together in response to movement of the motor relatively to its supporting casing. The flywheel is adapted to provide sufficient energy such that the resultant resistive torque between the workpieces on initial contact is reduced to be substantially the same as or less than the driving torque of the drive means.
