Bridge Factory Innovation Tsu Works(Bridge Fabrication using High Speed Rotaing Arc Welding Robots)

Abstract

Based upon "Factory Innovation Program FA2l", some robots assembly lines for bridge fabrication had been completed in NKK Tsu Works. In the box girder pannel line, the I-girder line and the transverse rib line, 26 welding robots which adopted the high speed rotating arc 'gelding process have been displaying the special capability and effect. In order to save the teaching operation for robots, we have developed the teachingless robot data system using the own CAD/CAM system "NEW BRISTLAN."
