Abstract:
1. A method for resurfacing a worn railway wheel substantially to an original profile, comprising the steps of: maintaining a welding device spaced from the worn railway wheel, the worn railway wheel defining an axis; displacing at least one of the welding device and worn railway wheel about the axis for continuous revolving displacement therebetween at a predetermined rate; selectively actuating the welding device and concurrently adjusting axial and radial displacement relative to a wheel center between the welding device and the railway wheel, the welding device being thereby controlled over a plurality of revolving passes to adaptively aggregate a plurality of annular beads formed from a welding material radially and axially displaced along a circumferential surface of the worn railway wheel having a curved profile, the welding material being applied during the continuous revolving displacement to form a welded layer of varied thickness on the circumferential surface, the circumferential surface having a flange and a tread surface, each annular bead extending to substantially encircle a portion of the circumferential surface, whereby the welded layer forms a curvilinear profile tapered away from the flange; and surface processing the welded layer to form a substantially uniform surface to substantially reconstitute the worn railway wheel to the original profile.
