Abstract
A method for joining a carburized steel workpiece to a cast iron workpiece is provided that includes tempering a localized area of the carburized steel workpiece, machining the localized area to reduce carbon content, and welding the carburized steel workpiece to the cast iron workpiece at the localized area. The tempering may be performed by induction heating and results in a hardness profile of the localized area of less than 50 HRC.
