Automatic Dual-face Spot Welding Machine
Automatic dual-face spot welding machine works as a high-speed spot welder to weld nickel plates onto positive or negative ends of cylindrical lithium-ion cells, so that you could get desired serial connection and parallel connection on a group of cylindrical li-ion cells.
This automatic dual-face spot welding machine is pneumatically driven so that the contact pressure on each welding point is consistent. By applying constant pulse current, this machine can ensure consistant welding quality on all welding points, and this is very critical for the quality and reliability of a finished lithium-ion battery pack.
This automatic dual-face spot welding machine has very high welding efficiency. And it’s very easy to change the fixture and parameters when you need to weld another pattern of lithium-ion battery packs. Moreover, it does not only support dual-face welding operation simultaneously according to set data, but also can be set to weld at one face only. In another word, it gives flexibility to fit changing demands in real lithium-ion battery production process.
