With the demand of long-distance pipeline for high-efficiency welding becoming increasingly high, root welding—— the key link in the welding process——is more and more concerned. The quality and speed of root welding are the bottlenecks for development of effective welding technology. The pipeline internal circumferential automatic welding machine of the PIW series is an integration of machinery, electrical control and pneumatics. The integrate-designed structures of its counterpart system and welding system can allow the lineup and root welding to be completed on concentration in the large-diameter pipeline welding construction. Engineering application shows that the pipeline internal circumferential welding machine of the PIW series is characterized with quick speed, good quality and high efficiency, desirably solving root welding problems and satisfying the demand of the existing pipeline construction for high root welding quality. Localization of the pipeline internal circumferential automatic welding machine of the PIW series has not only made a breakthrough in development of high-efficiency welding technology, but also broken foreign technological blockage and price monopoly, satisfied the demand for bevel form and precision in the pipe-end automatic welding technological sector, effectively improving the technological level and economic results of China’s pipeline construction.
