Title:

ULTRASONIC FLAW DETECTION DEVICE AND METHOD FOR CONTROLLING SAME

Document Type and Number:

WIPO Patent Application WO/2020/213038

Kind Code:

A1

Abstract:

Provided is an ultrasonic flaw detection device 2 comprising a flaw detection unit (22) for transmitting and receiving ultrasound, a swinging mechanism for supporting the flaw detection unit (22) such that the same can swing around a swinging axis, and a locking mechanism for switching between a swinging state and a locked state. The ultrasonic flaw detection device 2 controls the locking mechanism and swinging mechanism such that when the flaw detection unit (22) is moved along a direction (TL2) tangential to a surface (41) to be inspected from a position removed from a first end part (E1) of the surface (41) to be inspected to a lock release position (Prl), the flaw detection unit (22) is put in the locked state such that a direction (TL1) tangential to a contact surface (22bA) and the direction (TL2) tangential to the surface (41) to be inspected coincide, and the flaw detection unit (22) is switched from the locked state to the swinging state after the flaw detection unit (22) reaches the lock release position (Prl).
