The invention relates to the technical field of battery sealing nail welding, and provides a battery sealing nail welding defect repairing method. The repairing method comprises the following steps: acquiring an aluminum wafer of which the diameter is greater than that of a liquid injection hole of the battery top cover; removing the sealing nail at the liquid injection hole of the top cover of the battery; cleaning a liquid injection hole area; carrying out penetration type stitch welding by taking the wafer as an upper layer and the battery top cover as a lower layer to form a welding seam for melting the wafer and the battery top cover into a whole; and treating the welding seam and the wafer, enabling the outer surface of the wafer to be flush with the outer surface of the battery top cover, and enabling the liquid injection hole area not to be visually recognized. According to the repairing method, the aluminum wafer and the battery top cover are subjected to penetration stitch welding, and the welding seam and the surface of the wafer are treated, so that the welding defect of the sealing nail is repaired, the situation that the battery is degraded and scrapped due to poor welding or appearance defect of the sealing nail is avoided, and the quality requirement of the battery is met.
