Abstract： As an important component，wheel hub is very important for vehicle driving stability，safety and operation. Aiming at the low quality and low production efficiency of small domestic wheels manufacturers using the traditional manual welding way，a new type of automatic welding system was put forward using exiting welding equipment. The PLC was utilized as the control system which the development of human-computer interaction program and welding master program was included. In the girth weld welding process，automatic seam tracking system was used and MAG welding of high-quality was adopted，which can easily adjust the welding angle and speed and improve the reliability. The results indicate that the welding system improves the welding quality and production efficiency greatly and reduces costs and labor intensity.
