Abstract
A method and an apparatus for mobile repair of a stationary rotor seals of a turbo machine is provided. The method includes the following steps, 3D-scanning of the stationary seal, generation of 3D-model of the stationary seal, removing of the damaged spots of the seal using laser cutting, and generating a new seal at the repair spot by use of a second process head, which generates the seal by laser powder cladding. The apparatus includes a 3D-scanner, a cutting tool, and a first process head and a second process head.
