The sealing welding of square battery cap is a crucial step in battery manufacturing. The seal quality and weld strength directly impact the overall quality and safety of the battery, requiring high stability throughout the welding process and strong post-weld strength. Due to the long and varied welding routes of square battery covers, various welding defects can easily occur, making simple detection methods insufficient.

Welding is OK
Defect Case

ALPAS-WDD can monitor the entire welding process and detect different types of defects. In this case study, the battery box requires welding along the four sides in a specific order. The system identified four defects at points A, B, C, and D along the welding path, each representing a different type of defect.
