4 FAQs about [Battery steel shell welding inspection items]

Why is it important to monitor welding defects?

Welding quality plays a vital role in the durability and effectiveness of welding structures. Therefore, it is essential to monitor welding defects to ensure welds quality. Manual inspection, analysis and evaluation of welding defect images is difficult due to the non-uniformity in their shape, position, and size.

Why is laser welding used in lithium ion batteries?

Laser welding is widely used in lithium-ion batteries and manufacturing companies due to its high energy density and capability to join different materials. Welding quality plays a vital role in the durability and effectiveness of welding structures. Therefore, it is essential to monitor welding defects to ensure welds quality.

Why do we need deep learning to identify welding defects?

Manual inspection, analysis and evaluation of welding defect images is difficult due to the non-uniformity in their shape, position, and size. Hence the use of deep learning techniques to identify welding defects is more accurate and reliable due to the adequate training data samples, which helps to identify welding defects with greater accuracy.

Is AdaBoost a good approach for solder junction inspection?

Xie et al. developed an improved adaptive boosting (AdaBoost) and decision tree-based inspection approach for solder junctions. Although this approach obtained good accuracy, it relies on manual knowledge to extract the relevant features, thus reducing the execution efficiency.
