Zusammenfassung:	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.
