AI inspection of battery seal-pin welds at Liyang
CATL reported 100% defect detection in seal-pin welding at its Liyang plant
Problem
Battery manufacturing required consistent quality and precise inspection of seal-pin welds. CATL also used helium-leak testing in its inspection process.
Approach
CATL developed a quality-inspection model using a high-precision 3D camera, AI and edge computing. The system operated in the seal-pin welding process at its Liyang plant. CATL said the deployment eliminated helium-leak testing for that process.
Results
Takeaway
A targeted vision system replaced a separate test in one manufacturing step. The reported detection rate applies to seal-pin welding.
