ABSTRACT:
A method for attaching a metal wheel disc to a wheel rim formed from a metal which is dissimilar to the wheel disc metal. A layer of metal which is compatible for welding to the metal forming the wheel disc is thermally sprayed onto an outboard portion of the wheel rim to form a weld anchor. The wheel disc is positioned adjacent to the sprayed metal layer and welded thereto. The wheel disc also can be cast or forged over the sprayed metal layer with the wheel disc bonding to the sprayed metal layer to form a secure air-tight seal between the wheel disc and the wheel rim. Alternately, a metal filler compatible with both the metals forming the wheel disc and wheel rim is thermally sprayed onto the wheel rim and the wheel disc brazed thereto.
