INSPECTION METHOD OF TURBINE ROTOR

摘要

PROBLEM TO BE SOLVED: To provide an inspection method of a turbine rotor that can inspect the turbine rotor for internal cracks without detaching turbine blades from the turbine rotor.SOLUTION: An inspection method of a turbine rotor according to the present invention includes: a first step that measures gaps between turbine blades and the turbine rotor to identify regions to be inspected in the turbine rotor; and a second step that performs a hammering test of the identified regions to be inspected to determine the presence or absence of internal cracks in the turbine rotor.
