Repair of honeycomb sealing elements on turbine discs involves applying suitable molten metal alloy to already reassembled sealing bridge using laser beam directed at sealing element

摘要

The method involves applying a suitable molten metal alloy to the already reassembled sealing element (2), whose original material can not be welded, or can only be welded to a limited extent, using conventional welding techniques. The alloy is melted and applied by a laser beam (4) directed at the sealing element in a protective gas atmosphere.
