Abstract
This welding state determination system acquires, for each weaving cycle, a characteristic amount that pertains to a physical quantity that changes according to the cycle of a weaving operation. A degree of abnormality is calculated based on an observation value that is the characteristic amount acquired in one cycle, and the average and standard deviation of a plurality of past values that are the characteristic amounts acquired prior to the one cycle. A welding state is determined based on the calculated degree of abnormality.
