文摘The difficult problem of automatically welding nipples onto the header is first analyzed in this paper, and then the overall structure and operating principle of the robot working unit are introduced. The robot and the measuring device are located by employing the traveling lorry, and this unit enables the robot to adjust the tracks according to the errors received from the measuring device, and then the nipples are welded properly. This paper emphases on the development of the master-slave control system, in which the prograrmmable Logic Controller (PLC) is used as the master computer.
