The present invention relates to a water immersion ultrasonic testing apparatus. The water immersion ultrasonic testing apparatus according to the present invention is an apparatus for a water immersion ultrasonic test detecting defects of a subject which comprises: a probe detecting the defects by using ultrasonic waves; a distance adjusting unit adjusting the distance between the probe and the subject as connected to the probe; and a laser irradiating unit irradiating a laser to an area where the ultrasonic waves reach the subject. Accordingly, provided is the water immersion ultrasonic testing apparatus which can check the ultrasonic waves reaching the subject with the naked eye by using the laser, and reduce errors by irradiating the ultrasonic waves to an accurate area by allowing a travelling path of the laser to be converted. |
