Claim:
1. An apparatus comprising: a multi-motor friction welding drive system comprising: an actuator being connected axially to the drive shaft of the mult-motor friction welding drive system, wherein the actuator further comprises: a chuck being connected axially to the drive shaft of the actuator; and a boss being mounted axially to the chuck, wherein the hydraulic ram of the actuator is operable to apply a second pressure to the thrust bearing which then applies a pressure to the drive shaft of the actuator, which in turn applies a third pressure to the chuck and the boss, the thrust bearing allows the drive shaft of the actuator to rotate under the second pressure of the hydraulic ram of the actuator while allowing an axial force to be applied to the chuck and a fourth pressure on the boss is transferred to a valve during friction welding, as the boss is driven into the valve during the friction welding, the piston and the hydraulic ram of the actuator absorb a spatial difference, wherein the first pneumatic motor and the second pneumatic motor are mounted symmetrically to the platform, wherein a controller is connected to the first hose and second hose and the first compressed air source and second compressed air source are connected to the controller.
