Abstract
An ultrasonic measurement method includes: a measuring point setting step of setting an arbitrary measuring point near a weld portion inside of steel material and assuming a virtual reflecting surface that includes the measuring point and is parallel to a weld line direction; a focused beam setting step of transmitting ultrasonic waves of a shear wave mode and focusing onto the measuring point via a coupling medium at a predetermined incident angle with respect to the virtual reflecting surface; a detecting step of detecting reflected waves of the transmitted ultrasonic waves at a boundary between a base metal portion and the weld portion; and an evaluating step of evaluating a shape of the weld portion based on the reflected waves.
