ABSTRACT:
A forming roll includes a base component having an angularly extending surface thereabout, a solder material applied to the surface and a wear ring on the solder and shaped to complement the angled surfaces of the base component. The Base component and the wear ring are made of materials with different thermal expansion coefficients so that when the parts are heated and then cooled a compressive strain results.
