The invention relates to a
spot welding quality control method for a galvanized steel plate for an automobile. The
spot welding quality control method comprises the following steps that S1, the influence of
welding selection process parameters on the
welding quality is analyzed, and the process parameters are optimized; S2, the influence of
welding selection materials on the welding quality is analyzed; S3, the influence of a welding selection
electrode cap on the welding quality is analyzed; and S4, the welding quality is optimized by adopting a current
gain compensation method. According tothe
spot welding quality control method, the influence of the
welding process parameters, welding base materials, spot welding electrodes and the like on the welding quality is studied, and the spot welding quality is controlled by an appropriate method, so that the welding spattering and burrs are reduced, the welding spots are prevented from being over-burnt, the electrodes are prevented from being adhered, and the purposes of improving the strength and the appearance surface quality of the welding spot welding spots and improving the quality of the whole vehicle are achieved; and meanwhile,the production environment of a workshop is also improved, the labor intensity of workers is relieved, the production period is shortened, the production cost is reduced, resources are saved, and themarket competitiveness of enterprises is improved.
