An Algorithm and Simulation for the Automatic Welding of Battery Cover

In view of the current welding industry, there is no automated programming tool for the welding path of square battery cover. According to differential geometry theory, the principle of nonlinear error is analyzed. Then a simplified model for nonlinear error is established. Based on these, an efficient algorithm based on nonlinear error is proposed. According to the proposed algorithm, two instantiation of the algorithm are presented. Therefore, the proposed algorithm is simple, reliable, and efficient. It adapts to the requirement of two mainstream spuare battery covers perfectly.
