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.
