6 FAQs about [Battery welding quality assessment report]
Do high-volume production requirements affect welding performance in battery assembly?
Moreover, the high-volume production requirements, meaning the high number of joints per module/BP, increase the absolute number of defects. The first part of this study focuses on associating the challenges of welding application in battery assembly with the key performance indicators of the joints.
How to evaluate power batteries after welding?
At present, most of the post-welding quality evaluation of power batteries is mainly carried out by manual visual inspection, which is bound to cause low detection efficiency and high labor costs, making it difficult to meet the requirements of modern welding production for high efficiency and high quality.
What is quality assurance for battery welding applications?
The quality assurance for battery welding applications is still in its infancy. Commercial solutions exist, but dedicated solutions are based on end-of-line approaches, while online solutions tend to address the generic quality issues of a specific welding process.
Are there accessibility issues with battery welding?
This means that, on the one hand, there may be accessibility issues as the testing is performed on already assembled modules or packs, and on the other hand, key performance indicators for battery welding applications, such as electrical and fatigue performance of the joints, are not served.
How does welding instability affect the performance of power batteries?
However, on large-scale automatic production lines, on-site uncertainties such as material inhomogeneity, residual impurities, and parameter fluctuations increase the welding instability and easily lead to welding defects, which will seriously affect the quality and performance of power batteries [ 3, 4 ].
Can weld region parameters be extracted from power batteries?
It can be seen that the framework proposed in this paper can effectively extract the weld region parameters from the welding images on power batteries. In addition, the accuracy of the welding parameter extraction relies heavily on the results of the segmentation model in the previous section.
