Patent number: 7967183Abstract: The invention relates to a method for repairing components comprising a base material with an oriented microstructure, wherein the repair point comprises a correspondingly oriented microstructure as the surrounding base material. According to the inventive method, solder is applied in the region of a point which is to be repaired and is soldered to the component by means of a heating effect produced by a device. A temperature gradient, i.e., approximately a temperature characteristic, is produced during the heating effect, said temperature characteristic ranging from a high to a low temperature in the region of the point which is to be repaired.Type: GrantFiled: January 28, 2005Date of Patent: June 28, 2011Assignees: Siemens Aktiengesellschaft, MTU Aero Engines GmbHInventors: Dirk Goldschmidt, Matthias Oechsner, Michael Ott, Uwe Paul, Ursula Pickert, Eckart Schumann, Beate Seiler, Robert Singer, Jan Steinbach, Andreas Volek, Volker Vosberg
