摘要： PROBLEM TO BE SOLVED: To provide a method for inspecting and diagnosing a turbine with high accuracy in a short time by discriminating harmfulness of a damage detected by the inspection based on the data directly obtained in the direct inspection.

The defect information of the part to be inspected is analyzed, based on the ultrasonic wave waveform data according to the result, obtained by aligning the ultrasonic wave waveform data to positions for each group of transmission oscillators and reception oscillators for computation (step ST5). Then, by determining the presence or absence of defects at the part to be inspected based on the color gradation display result and defect information analysis result, the flaw detection result is displayed (steps ST6, ST7).

In this case, one of the ultrasonic beams is reflected on one end side (crack opening position) of a flaw part (d). Then, the ultrasonic beams are once reflected from the inner surface of the thick-walled part and the same linear scanning is performed at a flaw detecting angle θ3 of refraction so that the ultrasonic beams are once reflected from the outer surface of the thick-walled part to arrive at the flaw inspecting target region R. In this case, one of the ultrasonic beams is reflected on the other end side (crack leading end position) of the flaw part (d).
