【Abstract】 The circumferential welding and the straight seam welding at all position can be realizable by using welding crawl equipment for all position together with the flexible metal band track. The properties of the control system play a decisive role on the welding quality. The program controlling system based on PLC , the drive system for controlling DC motor and the digital showing system has been developed in present work. The experiments show that whole system is stable and effective and its control precision can meet the requirement of welding process. $$$$更多还原
