摘要：
A welding inspection method has steps of: generating transmission laser light for generating an ultrasonic wave and transmitting the transmission laser light to an object to be inspected during or after welding operation for irradiation; generating reception laser light for detecting an ultrasonic wave and transmitting the reception laser light to the object to be inspected for irradiation; collecting laser light scattered and reflected at surface of the object to be inspected; performing interference measurement of the laser light and obtaining an ultrasonic signal; and analyzing the ultrasonic signal obtained by the interference measurement. At least one of the transmission laser light generated in the transmission laser light irradiation step and the reception laser light generated in the reception laser light irradiation step is irradiated onto a welded metal part or a groove side surface.
