摘要： PROBLEM TO BE SOLVED: To detect cracks in the inner surface of the cooling hole (formed in a blade) of the blade of a gas turbine with ample sensitivity.
SOLUTION: A two-vibrator type ultrasonic probe 12 is opposed to the moving blade 10 of the gas turbine and an ultrasonic wave is transmitted to the target inner surface of the cooling hole from the ultrasonic probe 12, by using a vertical flaw detection method to receive the reflected echo from the inner surface of the cooling hole. The ultrasonic probe 12 is scanned along the surface of the moving blade, while executing this flaw detection method to acquire the B scope display accompanied by the scanning of the ultrasonic probe 12. The presence of the crack of the inner surface of the cooling hole is determined on the basis the B scope display.

摘要： PROBLEM TO BE SOLVED: To automatically determine whether a tube is normal, by integrally evaluating the thickness data of a plurality of spots. SOLUTION: The thickness of the tube at each spot is measured with the ultrasonic flaw detection method, and the measured data are recoded in the memory device.

Related to the thickness data which is smaller than a predetermined thickness threshold level, it is determined that whether it is normal or that reevaluation is needed, by evaluating the axial direction based on a plurality of thickness data. Similarly, related to the thickness data, it is determined that whether it is normal or re-evaluation is needed by evaluating the circumferential direction, based on the plurality of thickness data. Furthermore, by evaluating the stress of the least thickness part, it is determined that whether it is normal or reevaluation is needed. Related to the thickness data which is determined that the reevaluation is needed, pitting evaluation is performed, and finally it is determined that whether the tube is normal or abnormal.
