At present, there is a general phenomenon, such as large fluctuation of welding precision, unstable welding, and so on, especially the spatial data of the robot is complex and not intuitive. Aimed at these problems, on the basis of the original welding system, the tool center position （TCP） correction new technology was added, the programmable logical controller (PLC) and robot network communication system were structured, and the multiple robot workstation linkage control were implemented. Aimed at the specialties of the stud welding gun head, the homemade gripper embedded measuring pin simplifying the debugging process, improve the accuracy of measurement.
