Abstract
In a method of repairing a structural component, especially a stator-side structural component such as a housing or a guide vane ring of a gas turbine, a damaged section is separated-out along a separating line and removed from the structural component, and a new section that replaces the removed damaged section is connected with the structural component by welding along the separating line to produce a weld seam. The damaged section is separated-out from the structural component so as to minimize the length of the separating line and thus the weld seam. Depending on the material thickness distribution of the component along the separating line, material is removed from the structural component to provide the most uniform possible material thickness along the weld seam. After connecting the new section with the structural component by welding, at least the removed material is renewed by laser powder deposit welding.
