Welding spot quality prediction method and device, storage medium and electronic device

The invention provides a welding spot quality prediction method and device, a storage medium and an electronic device.The method comprises the steps that welding process parameters of a welding group control system when a target workpiece is welded are collected, welding spot appearance pictures of the target workpiece are collected, and the welding process parameters comprise spot welding electrical parameters and quality data; the spot welding electrical parameters are filtered based on the quality data, and an optimized feature set is obtained; the optimized feature set is input into a pre-trained welding spot quality prediction model, a welding spot quality prediction result of the target workpiece is output, and the welding spot quality prediction model is a supervised learning model; the welding spot appearance picture is input into a pre-trained welding spot appearance prediction model according to the welding spot quality prediction result, the welding spot appearance defect of the target workpiece is
