CONSTRUCTION TECHNOLOGY FOR ARC WELDING OF LARGE-DIAMETER STEEL PIPE
More and more large-diameter steel pipes are applied in hydraulic engineering.Welding is critical for the quality control and service life during the installation of these steel pipes.Through comparison of a number of technological experiments in Lot 6 of the Hexi Branch supporting the South-to-North Water Diversion Project,a set of construction technology for welding of large-diameter steel pipes was summarized,thus accelerating the construction,meeting the technical indicator and quality requirements for welds and making the appearance superior and elegant.Welding parameters of steel pipes can be finally determined through steel pipe welding tests on site in order to guide the construction.
