SCOUT a seam tracker system designed for precise machining with the capability to position the axes of an industrial robot or gantry in space (three dimensions). This system was developed to meet the positioning accuracy of +/- 0.05 mm (+/- 0.0127 inch) and path speed above 20 m/min (800 IPM) for laser welding as well as e.g. sealing or gluing. With SCOUT system it is not necessary to define a welding path with the very time consuming teach-in process.
