The concept of RoboScan stands not only for the new KUKA remote laser welding head, but also for the fact that it is guided and controlled by a robot. With this remote laser system, the laser beam is guided to the welding point with a working distance of up to 1500 mm, which enables extremely short repositioning times between laser joints. Small reorientations of the optics result in large, fast motions of the operating point. With a variable focal length of 270 mm to 1500 mm, RoboScan is unique on the laser market, offering maximum flexibility in the 3D processing of components. The focus diameter and angle of divergence remain constant over the entire adjustment range, guaranteeing optimal process reliability. The focal length adjustment is integrated into the controller as an external robot axis.
