Steel Frame Welding Robot Systems and Their Application at the Construction Site
Two welding robot systems have been developed to rationalize steel–frame construction. Both systems consist essentially of two portable cartesian–coordinate welding robots mounted on a carriage together with their ancillaries. After the robots are mounted on a beam or column by an operator, they measure the groove shape of the joint seam, determine the optimal welding conditions, and carry out welding from the first to the last layer without operator intervention.
An important feature of the column–beam welding system is the curved torch, with which the robot can continuously weld the bottom flange of a beam through a scallop. Since the pantograph of the carriage can extend three floors, up to 12 joints can be welded from one carriage position.
In welding column–column joints, two robots traveling on a circumferential rail installed near the seam of a rectangular hollow section weld the joint in combination. The robots can continuously weld a seam containing corners without weld defects even in joints with a misaligned groove.
Each system has been applied to actual construction sites and has proved effective in stabilizing the quality of welds and in raising welding productivity.
