Method for repairing turbine vanes

摘要

The present invention discloses a method for repairing metal edges using wire and a braze alloy. Using this method, it is possible to restore a damaged metal edge to blueprint dimensions. In the preferred embodiment, the disclosed method relates to the restoration of damaged or worn turbine vanes. The method comprises a preparation step of cleaning and milling the edge of the base metal to be repaired. A repair wire is then placed along the edge, and a braze compound is applied to the junction of the base metal and the repair wire. A brazing step follows which integrates the base metal, the wire and the brazing compound. After standard finishing steps, the repaired vane meets blueprint specifications and is ready for use in a turbine.
