Abstract
The present invention provides a method for connecting a turbine blade or vane to a turbine disk or to a turbine ring. First, a connecting body is formed on the turbine blade or vane by supplying an additive suitable for fusion welding to a surface of the turbine blade or vane, melting the additive on the surface, with incipient melting of the surface, and allowing the additive and the surface to solidify. Then, the connecting body is connected to the turbine disk or to the turbine ring by means of a fusion welding process.
Claims19
A method for connecting a turbine blade or vane to a turbine disk or a turbine ring, wherein the method comprises:
- (a) supplying an additive suitable for fusion welding to a surface of the turbine blade or vane,
- (b) melting the additive on the surface of the turbine blade or vane, with incipient melting of the surface,
- (c) allowing the additive and the surface to solidify to form a connecting body on the turbine blade or vane;
- and
- (d) connecting the turbine blade or vane to the turbine disk or the turbine ring by directly fusion welding the connecting body to the turbine disk or the turbine ring.
