With the construction of UHV transmission lines

steel pipe towers have been widely used due to the advantages of clear structural force transmission

small amount of steel

small area

etc. The main components adopt neck flanges and straight seam welded pipes. The circumferential butt weld of neck flanges and steel pipes is one of the key processes of steel pipe towers. Aiming at the butt weld of steel pipe and flange in actual production

this paper introduces the application of automatic welding production line in steel pipe tower of transmission line

including preparation before welding

welding quality inspection and efficiency comparison. The application of automatic welding production line guarantees the weld quality

promotes the improvement of production efficiency and improves the labor environment.
