Abstract
A method of repairing a rail wheel including removing a selected segment of a rim of the rail wheel to provide a remaining segment having a first engagement surface, and providing a replacement workpiece including a replacement body element having a second engagement surface formed to mate with the first engagement surface. The replacement workpiece is positioned to define a predetermined gap between the first and second engagement surfaces. One or more heating elements are positioned in the predetermined gap, for induction heating, in a non-oxidizing atmosphere, of first and second heated portions of the remaining segment and the replacement workpiece, and the first and second engagement surfaces, to a hot working temperature, for plastic deformation thereof. The heating elements are removed, and the first and second engagement surfaces are engaged for plastic deformation of at least part of the first and second heated portions and the engagement surfaces.
