<p><P>PROBLEM TO BE SOLVED: To provide a flaw detector for a blade groove part of a turbine rotor capable of scanning a plurality of kinds of rotor disks having different angles of inclination of shoulders. <P>SOLUTION: A flaw detector 10 includes an ultrasonic flaw detection probe 12, a movable carriage 13 for moving the ultrasonic flaw detection probe 12 vertically, and a support 11 for supporting the ultrasonic flaw detection probe 12 and the movable carriage 13. The support 11 includes an ultrasonic flaw detection support 20 having a hollow part 20a, a shoulder contact body 30 connected swingably to an upper end part of the ultrasonic flaw detection probe support 20, and angle fixtures 40 for fixing a swinging angle of the shoulder contact body 30 with respect to the ultrasonic flaw detection probe support 20. The angle fixtures 40 can adjust the inclination of the shoulder contact body 30 in accordance with the angleαof inclination of a shoulder part 3. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
