Abstract
An apparatus for balancing an aluminum drive shaft uses a transition material to attach steel counterweights to the aluminum drive shaft. The transition material is disposed between an outer surface of the aluminum drive shaft and an inner surface of the steel counterweights. A resistance welding process is then applied to the aluminum drive shaft, the steel counterweights, and the transition material to resistance weld the inner surface of the steel counterweights to the outer surface of the aluminum drive shaft. The transition material has a first surface adjacent to the aluminum drive shaft and a second surface adjacent to the steel counterweights, with the first surface being aluminum and the second surface being steel. In a method of balancing an aluminum drive shaft, a resistance welding process is applied to the aluminum drive shaft, the steel counterweights, and the transition material to resistance weld the inner surface of the steel counterweights to the outer surface of the aluminum drive shaft.
