Laser welding defects detection in lithium-ion battery poles
In the situation when the laser pulse energy is high, it can lead to ''weldingholes'', ''continuousholes'', and ''burn'' defects. ''Weldingholes'' are holes that are created as a result of inadequate adjustment of the welding parameters. Conversely ''continuousholes'' refer to holes that are created continuously or successively.
