| 摘要 |
The invention relates to a method for repairing a structural component, especially a stator-side structural component of a gas turbine such as a housing or a guide vane ring, whereby a damaged section is separated-out from the structural component, and whereby a new section that replaces the damaged as well as separated-out section is fixedly or rigidly connected with the structural component by welding. According to the invention, the damaged section is separated-out from the structural component to be repaired in such a manner so that the length of a separating seam and therewith a later weld seam is minimized, whereby depending on the material thickness distribution along the separating seam, for providing a most uniform possible material thickness along the later weld seam, material is removed from the structural component, and whereby after the connecting of the structural component with the new section, at least the removed material is renewed by laser powder deposit welding.
