Abstract: Aiming at the problems of industrial robot welding path correction such as large error, low search accuracy and long correction time, a welding path correction method based on leapfrog algorithm is proposed. Firstly, the key components of the industrial welding robot system and its interaction are determined, and its control system and operation principle are analysed. Then calculate the total resistance and voltage change value of spot welding industrial robot, realise the change of position relationship in its running path by means of homogeneous transformation method, and determine the change of technical parameters of the robot under different rotation angles. Finally, the optimal path is searched globally, and the welding path of the welding industrial robot is modified by the idea of differential evolution. The results show that the proposed method can reduce the welding path correction error, and the correction time is short.
