Abstract
A method is available for repairing metallic components such as gas turbines, which have mechanically weight-carrying grooves, where the longitudinal edges of the grooves which exist on the component surface are largely in a plane and their actual contour deviates, at least locally, due to removal and/or displacement the component material from the desired contour. The method begins with abrasive blasting of the groove surfaces, followed by closing of the open groove ends by build-up welding, and subsequent filling of the grooves with soldering powder. The soldering powder is heated to liquefaction, then cooled and solidified in a vacuum, and the desired contour of the groove is then machined.
