METHOD FOR REPAIRING AND/OR REPLACING INDIVIDUAL ELEMENTS OF A GAS TURBINE COMPONENT

摘要

The invention relates to a method for repairing and/or replacing individual elements of a gas turbine component (10), particularly a blade or blade part arranged on a rotor support of a gas turbine, at least some of the components (10) being provided with at least one wear-resistant and/or erosion-resistant layer. The inventive method comprises the following steps: a) a coated or uncoated individual element that is damaged and/or needs to be replaced is removed from the component (10); b) a coated, partially coated, or uncoated replacement element (12) is provided; c) the replacement element (12) is fed and aligned relative to the component (10); and d) the replacement element (12) is connected to the component (10), corresponding contact areas (20, 22) of the replacement element (12) and the component (10) being connected by means of an inductive low-frequency or high-frequency pressure welding process.
