Abstract
A method for repairing a turbine nozzle segment having at least two vanes disposed between outer and inner bands includes the steps of separating the nozzle segment into a first singlet containing a repairable vane and a second singlet containing a non-repairable vane, and joining the first singlet to a newly manufactured singlet having a configuration that is similar to the second singlet.
