自动焊接生产线在输电线路钢管塔加工中的应用

Application of automatic welding production line in steel pipe tower processing of transmission line

随着特高压输电线路的建设,钢管塔因结构传力清晰、用钢量少、占地面积小等优点得到了广泛应用,其主要构件采用带颈法兰和直缝焊管,带颈法兰与钢管的环向对接焊缝是钢管塔加工工序关键之一,全部要求一级焊缝。针对实际生产中的钢管与法兰对接焊缝,介绍了自动焊接生产线在输电线路钢管塔中的应用,包括焊前准备、焊接、焊接质量检验及效率对比等。自动焊接生产线的应用保证了焊缝质量,提高了生产效率的提高,改善了劳动环境。

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, 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.
