ABSTRACT:
A method and an apparatus for repairing gas-turbine blisks uses an endoscope15provided with processing optics featuring a flexible light guide arrangement16. A laser source9is connected to a flexible optical fiber arrangement10, with a filler material feeder7for supplying welding flux via a flexible line8, with a water supply11connected to a flexible line12, and with an inert gas supply13connected to a flexible line16for supplying inert gas, with the flexible lines8, 12, 14, the flexible light guide arrangement16and the flexible optical fiber arrangement10being combined to form a flexible long repair implement17at least at its distal end areas.
