영문 초록

Remote Laser welding technology for manufacturing automobile body is studied. Laser welding system and industrial robot are used for consisting the robot based laser welding system. The laser system is used 1.6kW Fiber laser(YLR-1600) of IPG. The robot system is used HX130-02 of Hyundai Heavy Industry(payload :130kg). The robot based laser welding system is equipped with laser scanner system for remote laser welding. The welding joints of steel plate and steel plate coated with zinc are butt and lap joint. The laser welding tests are performed through the observation the bead on plate and cross-section of welding part. During the past three years the laser system was used 4kW Nd:YAG laser(HL4006D) of Trumpf and the robot system was used IRB6400R of ABB(payload:120kg). The new laser source, robot and laser scanner system permit to increase the processing speed and to improve the process efficiency. This paper introduces the robot based remote laser welding system to permit to resolve the limited welding speed and accuracy of the conventional laser welding system.
