多层金属薄板的超声点焊是锂电池制造的关键工艺。然而，焊接质量不一致仍然是多层USW的一个问题，这使得在线质量监测非常必要，以便为每个工件的焊接质量提供快速可靠的反馈。利用高频位移传感器监测超声电极夹紧方向的位移，建立其与焊缝质量的关系。结合激光扫描共聚焦显微镜、光学显微镜和电子背散射衍射（EBSD）表征的塑性变形和焊接质量变化，分析了位移信号的特征。此外，还研究了焊接参数对位移信号的影响。最后，建立了位移信号、塑性变形与焊缝质量之间的关系，该关系可用于多层焊接材料的在线质量监测。
Ultrasonic spot welding (USW) of multilayer metal sheets is a critical process of lithium battery manufacturing. However, inconsistent weld quality is still an issue in multilayer USW which makes the online quality monitoring very necessary to provide rapid and reliable feedbacks of each workpiece’s weld quality. In this work, the displacement of the sonotrode in the clamping direction was monitored by a high-frequency displacement sensor in order to establish the relationship with the weld quality. Features of displacement signals were analyzed combined with changes in the plastic deformation and welding qualities which were characterized by the laser scanning confocal microscopy, the optical microscopy and the electron backscattered diffraction (EBSD). Besides, effects of welding parameters on the displacement signal were studied. Finally, the relationship between the displacement signal, the plastic deformation and the weld quality was established which can be used for the online quality monitoring of the multilayer USW.
