Welding quality detection method for battery water cooling plate

The invention relates to a welding quality detection method for a battery water-cooling plate, and belongs to the technical field of battery water-cooling plates. The invention discloses a welding quality detection method for a battery water-cooling plate. The method comprises the following steps: coating a welding surface of a water-cooling plate sample with solidification glue; the coated water cooling plate sample is ground and polished, so that a welding metal surface is exposed; the exposed welding metal surface is placed in a hydrofluoric acid solution to be soaked, and the ground and polished welding metal surface is clearly displayed; and then the hydrofluoric acid solution is washed away with water, the washed water cooling plate sample is placed under a microscope to be observed, and the brazing quality is determined. According to the detection method, the welding surface of the water-cooling plate can be better exposed, so that the welding surface of the water-cooling plate is clearly visible, the
