Abstract: Tenons can be installed at the ends of turbine blades by applying a solid state bonding procedure such as a friction welding technique to join the tenons to the turbine blades. The tenons can be employed to assemble the turbine blades to one or more covers for the turbine blades. The tenons can be installed in connection with the restoration of tenons for turbine buckets in steam turbines and in connection with the renovation of rotor assemblies that include turbine blades secured to a common disk, tenons located at one end of respective turbine blades and one or more covers secured to the turbine blades by means of the tenons. In instances in which tenon remnants are present at the ends of the turbine blades, tenon enlargement elements can be joined to the tenon remnants by the solid state bonding procedure. The tenon installations can be carried out in situ.

Abstract: A method and system for use in facilitating relative movement between first and second components is provided. A first component engagement assembly is inserted into an opening in the first component. The first component engagement assembly is threadably coupled adjacent to a thrust member such that the thrust member extends through the first component opening. An end of the thrust member extends toward the second component. The first component engagement assembly couples in frictional engagement with an inner surface of the first component opening. When torque is exerted on the thrust member, the thrust member moves relative to the first component engagement assembly to exert, via the end of the thrust member, one of a thrust force and a traction force against the second component to move the second component relative to the first component.

Abstract: A method to repair a turbomachine including: assign blades and a shroud in a row of the turbomachine to a group; measure, for each blade in the group, a clearance between a tip surface of the blade and a surface of the shroud facing the tip surface; remove the blades and shroud from the row; calculate a difference between the clearance of associated each blade and a design clearance; determine, for each blade, if the difference may be minimized by adding material to the surface of the shroud; adding material to the surface of the shroud, wherein the addition of material to the facing surfaces results in the shroud having at least one dimension that exceeds an original design dimension of the shroud sections, and installing the group of the blades and the shroud with the added material to a row of a turbomachine, wherein at least one of the blades has at least one dimension that does not conform to an original design specification for the blade.
