Claim 10:
11. A processing method, comprising:
determination processing of determining a state of a weld by using a first image of at least a portion of a weld pool, the state including a first state and a second state, the second state being more unstable than the first state, the determination processing determining the weld to be in the second state when ripples exist in the weld pool, the weld pool being liquid and including melted metal;
correcting a condition when the weld is determined to be in the second state;
not correcting the condition of the weld when the weld is determined to be in the first state
calculating an evaluation value based on a pixel value of the first image, and the state is determined by comparing the evaluation value to a preset determination condition,
wherein the calculating of the evaluation value includes:
calculating a first value of a plurality of the pixel values of the first image, the first value being an average, a sum, or a weighted average; and
calculating a moving average and a fluctuation of the first values of a plurality of the first images, and

wherein the fluctuation is used as the evaluation value.
