Energy storage spot welding machine control method and system

The invention relates to an energy storage spot welding machine control method and system, and relates to the technical field of machining equipment. The method comprises the steps that the number of processed workpieces, the number of waiting workpieces and an electrode overall image are obtained; determining an electrode attachment part in the whole image of the electrode, and analyzing according to the electrode attachment part to determine the volume of the attachment; when the attachment volume is larger than the required analysis volume, the unit attachment volume is determined according to the number of processed workpieces and the attachment volume; the influence difference value volume is determined according to the influence machining volume and the attachment volume, and the number of feasible workpieces is determined according to the influence difference value volume and the unit attachment volume; judging whether the feasible workpiece number is smaller than the waiting workpiece number; if not,
