Abstract
Provided are a processing device, a detecting system, a processing method, a program, and a storage medium that obtain a position of a weld portion of a joined body with higher accuracy. A processing device according to an embodiment receives intensity data of a reflected wave obtained by transmitting an ultrasonic wave along a first direction toward a joined body. The device designates a weld portion of the joined body by using the intensity data. The device calculates a first center position of the weld portion in a first plane crossing the first direction.
Claims16
A processing device, configured to:
- receive, via a detector connected to the processing device, intensity data of a reflected wave obtained by transmitting an ultrasonic wave from the detector along a first direction toward a joined body, the detector configured to transmit the ultrasonic wave, detect the reflected wave, and transmit the intensity data to be received at the processing device;
- designate a weld portion of the joined body by using the intensity data, designating the weld portion including
- determining, at points in a first plane crossing the first direction, whether a peak corresponding to a lower surface of a first member of the joined body exists in a reflected wave intensity distribution in the first direction,
- determining that points at which the peak is not detected are joined, and
- designating a cluster of the points determined to be joined as the weld portion;
- calculate a first center position of the designated weld portion in the first plane crossing the first direction;
- calculate, in the first plane, a distance between the first center position of the designated weld portion and a second center position corresponding to a design position of the weld portion;
- and
- determine a goodness of the joined body by using the calculated distance.
