1. A processing system, comprising:
a processing device that
receives a detection result of a reflected wave from a detector, the detector including a plurality of detection elements arranged in a first direction and a second direction, the first direction and the second direction crossing each other, the detector performing a probe that includes transmitting an ultrasonic wave toward a welding object and detecting the reflected wave,
performs a first determination of determining a joint and a non-joint at a plurality of points along the first and second directions of the welding object based on the detection result, and
performs a second determination of determining an appropriateness of a result of the first determination based on the detection result or the result of the first determination, wherein
in the second determination, the processing device:
calculates a first evaluation value based on the detection result or the result of the first determination; and
determines the appropriateness of the result of the first determination by using the first evaluation value and a previous first evaluation value.
