Method of repairing metallic components having weight-carrying grooves, whose actual contour, after the removal or displacement of the component material, deviates from the desired contour, by applying a metallic additional material to the actual contour as well as by the removing machining to the desired contour. The method comprises the following steps for each groove: A) The mechanical abrasive blasting by means of a non-oxidic abrasive, B) closing of open groove ends by buildup welding, C) filling the groove with a soldering powder, without or with an additional material, which soldering powder melts at a lower temperature than the material of the component, the empty-volume fraction being compensated by an accumulation beyond the groove surface, D) heating the soldering powder in the vacuum to the liquefaction and joining with the component material, as well as cooling and solidifying in the vacuum, and E) machining to the desired contour by an extensive removal of the solidified solder.
