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.
