Abstract
A turbine component repair apparatus includes: a first die having male and female halves for clamping a first section of a turbine blade with a platform and a root portion of an airfoil, the first die having a recess shaped to receive the root portion and retain a faying surface thereof in predetermined alignment; and a second die having male and female halves for clamping a repair section which defines a tip portion of the airfoil, the second die having a second recess shaped to receive the tip portion and retain a faying surface of the tip portion in predetermined alignment. The first and second dies have mating front faces configured to align their bottom surfaces in a common plane. A alignment device is removably attached to the second die to temporarily align the repair section in the absence of the male half of the second die.
