Two kinds of welded joint plate specimens of carbon steel were employed. One kind had an inner defect which was a weld metal crack, and the other had no defect. Each specimen was 28mm thick and had a weld zone which was formed by TIG welding with argon inert gas. In the ultrasonic ...
So, the defects detection of laser welding is absolutely necessary to ensure the quality of the batteries. In this paper, we proposed an improved YOLOv7 algorithm for laser welding defect detection of battery pole. The algorithm adopts Conv2former to improve the model's capability to extract ...
