In this paper,a laser welding control system based on field programmed gated(FPGA)is designed.The system utilizes STM32 as an auxiliary chip to input parameters and control commands to the FPGA through a host computer and external buttons.With the advantage of the strong processing power of FPGA,the state of galvanometer,laser and motor can be controlled at the same time,and then the control of the whole welding process can be completed.Finally,the simulation test of the system is carried out,and the results show that the system can achieve the predetermined work.
