According to one embodiment, an inspection system includes a probe and a controller. The probe includes a plurality of ultrasonic sensors arranged in a first direction. The probe contacts a weld portion by moving in a second direction crossing the first direction. Each of the plurality of ultrasonic sensors transmits an ultrasonic wave toward the weld portion and receives a reflected wave. The controller detects a joint and a non-joint at a plurality of points along the first direction of the weld portion based on the plurality of reflected waves. The controller adjusts an angle of the probe around a third direction based on a number of the joints or the non-joints detected for the plurality of points. The third direction is perpendicular to the first direction and crosses the second direction.

Inspection system, control unit, control method, and storage medium

A three-dimensional ultrasonic inspection apparatuscan make increased inspection accuracy in comparison to the conventional apparatus and includes: an ultrasonic transducerdisposed m&#xd7;n piezoelectric vibrators in a matrix; a signal processing unitto receive, detect an echo, and generate a three-dimensional image data by processing an electric signal of the echo detected; a peak detecting elementto detect a first peak and a second peak of an intensity distribution of the three-dimensional image data in a depth (z) direction; a joint portion image creation unitto create a three-dimensional image of the joined areaby mapping z direction distance of the first peak and the second peak to x-y plane; a determination unitto determine whether the joined areais sound by two-step determination; and a display unitto display the three-dimensional image and the determination result, of the joined area
