Abstract
An ultrasonic inspection device includes: a vibration generating section that irradiates laser beam onto a first member to generate ultrasonic vibration; a detecting section that detects the ultrasonic vibration propagated from the first to a second members via a welded portion; and an analyzing section that analyzes the propagated ultrasonic vibration detected by the detecting section. The analyzing section obtains at least one of frequency and wavelength of the ultrasonic vibration detected by the detecting section upon when a displacement in the second member in a thickness direction becomes maximum. The analyzing section obtains a cross sectional dimension of the welded portion from a correlated relationship of the cross sectional dimension of the welded portion obtained in advance at a position on a surface of the second member on the first member side and the at least one of the frequency and wavelength of the ultrasonic vibration.
