Abstract
A linear friction welding system includes a processing circuit configured to execute program instructions stored in a memory to control a first motor using one of a torque and speed control, placing a plurality of timing gears in a configuration wherein a fixed projection of one of the timing gears is at a trail position of a slot of another timing gear such that two power shafts of a cam assembly are rotating in phase and a ram is motionless. The processing circuit further controls a hydraulic press to generate a pressure between two components to be welded with the power shafts rotating in phase, and controls the second motor using the one of the torque and speed control to place the timing gears in a second configuration whereat the fixed projection is at a lead position of the slot thereby forcing the ram to oscillate.
