Abstract:
A method of operating a linear friction welding system in one embodiment includes positioning a phase change assembly driven by a motor in different configurations to establish different phase relationships between two eccentrically engaged power shafts while one of the power shafts is driven by the motor and the other power shaft is driven by the phase change assembly. In one phase change assembly configuration a ram operably connected to one of two components to be welded does not vibrate when the first power shaft and the second power shaft rotate while in another phase change assembly configuration the ram vibrates. Pressure between the two components is controlled to provide scrub pressure when the ram vibrates and forge pressure when the ram is no longer vibrating.

Claim (Index 1):
A method of operating a linear friction welding system including (i) a ram configured to vibrate along a welding axis, (ii) a cam follower operably connected to the ram, (iii) an eccentric including an eccentric outer periphery operably engaged with the cam follower, and an inner periphery, (iv) a first power shaft slidingly engaged with the eccentric, (v) a second power shaft eccentrically engaged with the inner periphery, (vi) a first timing component configured to drive both the second power shaft and a phase change assembly drive shaft, (vii) a motor configured to drive the first timing component, and (viii) a phase change assembly driven by the phase change assembly drive shaft, comprising:\n positioning the phase change assembly in a first configuration thereby establishing a phase relationship between the first power shaft and the second power shaft whereat the ram does not vibrate when the first power shaft and the second power shaft rotate; driving the timing component with the motor, driving the first power shaft and the phase change assembly with the timing component with the phase change assembly in the first configuration; driving the second power shaft with the phase change assembly while the phase change assembly is in the first configuration; establishing a scrub pressure between two components to be welded with the phase change assembly in the first configuration while the first timing component is being driven; establishing a second phase relationship between the first power shaft and the second power shaft by moving the phase change assembly to a second configuration while the first power shaft and the second power shaft are being driven, thereby causing the ram to vibrate along the welding axis while the scrub pressure is applied; establishing the first phase relationship between the first power shaft and the second power shaft by returning the phase change assembly from the second configuration to the first configuration; and establishing a forge pressure between the two components with the phase change assembly returned to the first configuration.
