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;
adaptively aggregating annular beads formed from a welding material along a circumferential surface of the worn railway wheel to form a welded layer, the circumferential surface having a flange and a tread 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;
wherein the worn railway wheel is mechanically disturbed to form a plurality of transverse grooves on the circumferential surface before the step of adaptively aggregating the annular beads.

Abstract
A wheel resurfacing method and system for resurfacing a worn track wheel to its original profile are disclosed. 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 applied to the welded layer to form a substantially uniform surface to reconstitute the worn railway wheel to its original profile.
