Description

[0002] The top cover and the lower shell of a battery are generally connected through laser welding, and a weld is formed at the connection between the top cover and the lower shell. After welding is completed, the weld needs to be detected to check whether there are defects such as welding holes, virtual welding, incomplete welding tracks, and welding deviation. Welding defects can reduce the performance of the battery (for example, the capacity, voltage, and charge / discharge efficiency of the battery), reduce the stability of the battery, and easily cause the shell to fall off and cause short circuit and other dangerous accidents, which poses a safety hazard.
