A new large-scale steel bar mesh welding method using vision-guided robot system and application on bridge tower construction

Manufacturing of large steel bar reinforcement semi-finished parts becomes more popular as assembly construction demands of bridge tower grow. However, the popularity of industrial device like welding robot that is usually welcomed in mass production is hindered by the traditional usage and cost it brings. In this paper, we proposed a newly welding method for spatial irregularly arranged steel bar intersections by using vision-guided multi-axis motion robot, wherein composition of robot system and welding methods are introduced. Finally, the practicability and effectiveness are verified through a typical bridge tower engineering application.
