1. A linear friction welding system, comprising:

  • a ram configured to oscillate along a welding axis;

    a first power shaft operably connectable to the ram through a vibrating assembly;

    a second power shaft operably connectable to the ram through the vibrating assembly;

    a first motor configured to drive a first power timing gear, the first power timing gear fixedly connected to the first power shaft;

    a second motor configured to drive a second power timing gear, the second power timing gear fixedly connected to the second power shaft; and

    a first slave timing gear operably connected to the first power shaft and the second power shaft, the slave timing gear in fixed rotational relationship to the second power shaft, and in variable rotational relationship with the first power shaft, the first slave timing gear configured to be driven by the first power shaft in a first configuration, and configured to be driven by the second power shaft in a second configuration, wherein in one of the first and second configuration, the first and second power shafts are operably connected to the ram through the vibrating assembly, and in the other of the first and second configuration, the first and second power shafts are not operably connected to the ram through the vibrating assembly.
