Abstract

A method is provided for laser hardening a substantially cylindrical surface of a workpiece, e.g. the wheel rim of the wheel disk of a track-guided railway wheel, at least with a partial width of its wheel tread and/or of the side of its flange facing the wheel tread, which are subjected to abrasion. The method includes projecting a laser spot, by means of a laser source, onto the surface of the wheel disk which is to be processed, producing relative movement between the surface and the laser source by rotating the wheel disk about its axis of rotation, scanning the laser beam with respect to the surface which is to be processed, during the rotational movement, and modulating the laser beam in accordance with various criteria, for example with respect to its power and/or its scanning speed and/or its laser spot size and/or its scanning pattern.
