Research and design of welding seam tracking control system

To solve the problem of welding automation, based on ARM+FPGA technology, this paper proposed a welding seam tracking control system design scheme, the whole process includes image acquisition and motion control. The system adopts CMOS image sensor to collect image information of welding seam for denoising, curve fitting, calculation of deviation amount, control motor to adjust the position of the welding torch in real-time, and achieve the purpose of automatic welding. The test results show that the system can perform image processing accurately, locate welding seam and realize automatic welding tracking [1].
