Abstract

The invention relates to a method for repairing components that consist of a superalloy. The method comprises the following steps: a solder material is applied to the repair site; the repair site with the applied solder material is heated until the latter melts; and the melted solder material is left to solidify. A powder blend, whose average composition corresponds to the component alloy constitutes the solder material, the blend comprising at least one elementary powder of the component alloy as one powder type and/or a pre-alloy of the component alloy.
