FRICTION OR INERTIA WELDING APPARATUS ABSTRACT OF THE DISCLOSURE Apparatus adapted for performing either friction or inertia welds comprises a rotary holder for holding one workpiece to be welded and a non-rotary holder for holding a second workpiece that is to be welded to the first work- piece, the two workpiece holders being relatively movable to enable the workpieces to be forced into engagement with one another. The rotary workpiece holder is driven by means of a driving motor through the intermediary of drive transmitting means comprising a torque converter, a fly- wheel, a variable transmission, a clutch, and a brake. The flywheel is interposed between the torque converter and the transmission and upstream of the clutch, thereby enabling only so much of the flywheel's energy to be util- ized as may be necessary to effect the weld, following which the clutch may be disengaged, thereby permitting the driving motor and the torque converter to replenish the flywheel's energy during removal of the welded work- pieces from their respective holders.
