['1. A welding state determination system that determines a welding state in arc welding by a weaving operation in which a welding torch is oscillated in cycles, the welding state determination system comprising: an acquisition unit configured to acquire, for each cycle, a characteristic amount that pertains to a physical quantity that changes according to the cycle of the weaving operation; a calculation unit configured to calculate a degree of abnormality based on an observation value that is the characteristic amount acquired in one cycle by the acquisition unit and an average and standard deviation of a plurality of past values that are the characteristic amounts acquired prior to the one cycle by the acquisition unit; and a determination unit configured to determine the welding state based on the degree of abnormality calculated by the calculation unit.', '11. The welding state determination system according to claim 1 or 2, further comprising: an abnormality communication unit configured to notify the abnormality when the determination unit determines that the welding state is abnormal.']
