Abstract: According to one embodiment, an estimation device includes a processor. The processor accepts information. The information is acquired by each of a plurality of ultrasonic sensors transmitting an ultrasonic wave in a second direction toward a weld portion and receiving a reflected wave. The ultrasonic sensors are arranged in a first direction. The second direction crosses the first direction. The processor estimates a range of the weld portion in the second direction based on an intensity distribution of the reflected wave in the second direction. The processor calculates a centroid position of an intensity distribution of the reflected wave in the first direction for each of a plurality of points in the second direction, and estimates a range of the weld portion in the first direction based on a plurality of the centroid positions.

Abstract: 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.
