ELECTRODE TAB STRUCTURE AND WELDING TOOLING

An electrode tab structure and a welding tooling are provided in the present disclosure. The electrode tab structure includes multiple electrode tab units stacked and pre-welded together, and the electrode tab structure includes a first end face and a second end face arranged opposite to each other. The first end face of the electrode tab structure is configured to be abutted against a welding head, and the second end face of the electrode tab structure is configured to be abutted against a welding platform. A difference between a highest point and a lowest point of a metallographic section of the first end face in a first direction being H a difference between a highest point and a lowest point of a metallographic section of the second end face in the first direction being H and HH
