  • Method for reconditioning a turbine blade
    Patent number: 9999948
    Abstract: A method is provided for reconditioning a turbine blade. The turbine blade includes a blade airfoil which extends longitudinally and into the hollow inner space of which inserts can be inserted in the longitudinal direction of the blade for distribution and guiding cooling air which flows in the inner space. The inserts with a rib engage with sealing effect in a U-shaped sealing groove which is machined out on the inner wall of the blade airfoil and extend in the longitudinal direction of the blade. A damaged sealing groove is reconditioned by the sealing groove being removed from the inner wall of the blade airfoil, forming a slot, by an insertion strip, which is provided for sealing, being inserted into the slot, and by the insertion strip, which is seated in the slot, being connected in a materially bonding manner to the inner wall of the blade airfoil.
