Method and system for retreading track wheel
First Claim
1. A method for resurfacing a worn railway wheel substantially to an original profile, comprising the steps of:
- supporting the worn railway wheel and a welding device, whereby the worn railway wheel and the welding device rotate one relative to the other 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 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 and form a welded layer of varied thickness thereon, the circumferential surface defining at least 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 along the circumferential surface; and
,surface processing the welded layer to define a substantially smooth surface contour and thereby substantially reconstitute the worn railway wheel to the original profile.

Abstract
A wheel resurfacing method and system for resurfacing a worn track wheel to its original profile are provided. The system comprises a support for maintaining the worn railway wheel, a welding device, a controller, and a surface processing device. The worn railway wheel'"'"'s circumferential surface defining a flange and a tread surface is reconstituted using a welding material. The welding device and the worn railway wheel rotate one relative to the other at a predetermined rate to adaptively aggregate annular welding beads along the circumferential surface to form a curvilinear profile slanted away from the flange. A surface processing device is then actuated to smooth the welded layer to form a substantially uniform surface to reconstitute the worn railway wheel to its original profile.
