In a method for beam welding on components (2) with a laser beam (4) or electron beam generated by a beam source (10), the heat treatment of the welded component required to remove stresses is integrated into the welding process. In a work cycle combined with the welding process, a regulated heat supply to a selected region (6,8) takes place, according to its residual heat resulting from the welding process and the predicted stresses in that region, using the residual heat remaining from the welding process following the welding process from the same or other beam source(s). The welding region is cooled in a controlled manner, so that welded components which are likely to be subject to high stress in use, provided for example for a aircraft engine, can be made available without inherent stresses and with the desired microstructure in a single - combined - work step. On the one hand, the method is cost-effective because the labour input is small due to the combined processing in one and the same device. On the other hand, the outlay on equipment is reduced, since a separate expensive heat treatment device, in which the component is either completely or locally heat-treated, may not be required or could be required for a substantially shorter period. Moreover, a post-treatment of the component, for example by shot-blasting, which may be necessitated by the separate heat treatment of the component, is potentially dispensed with. |
