2 ROFIN SWS THE PRODUCT 3D Scanner Welding on the Fly The Scanner Welding System (SWS) is a fast beam deflection system used for robotically guided multi-spot welding. The SWS has been specifically developed for connection to the ROFIN fiber laser series. The fiber laser is integrated into fully automated welding systems, in combination with a 3-axis scanner and the RobotSyncUnit. Complex shaped 3D components can be welded with the flexibility of the SWS. By coupling all axes of the scanner with those of the robot as a guiding machine, the system commands a total of nine selectable axes. Regardless of whether we are talking about spot-, circular-, wave- or stitching seams the seam geometry is freely programmable and can therefore be adjusted to strength and component requirements. Through very fast arrival at the next welding position and therewith very short laser down-time non-productive welding times can be reduced virtually in full, which leads to a fast return on investment. The real time processing of the geometric data through the control, as well as through the rotating mirrors in the scanner head enables extremely fast positioning of the laser beam of < 10 ms within the working field. The robot movements and speeds are optimized by complete offline programming of the application. Software functions also calculate the path inaccuracies of the robot so that repeat accuracies in the range of < 0.1 mm are possible. ROFIN SWS T H E P O W E R O F L I G H T

3 ROFIN SWS THE TECHNOLOGY Laser The high brightness fiber lasers of the ROFIN FL Series with a wavelength in the range of 1 µm are the heart of the Scanner Welding System. The excellent beam quality allows the efficient use with dynamic beam scanner systems such as the SWS. Scanner The Z-adjustable collimator unit, two rotating deflection mirrors and the focusing device are integrated in the scanner head. The beam of a fiber laser is transmitted to the scanner head via an optical fiber. The scanner allows use of the laser as a highly dynamic flexible tool for material processing and enables fast, precise, fine positioning of the laser spot in the space. For this purpose, the laser beam is positioned quickly, precisely and reliably in three dimensions with the help of moveable mirrors and optical elements. RobotSyncUnit The RobotSyncUnit, which ensures efficient planning and set-to-work, achieves optimum cycle times and offers the ideal solution for programming, controlling and monitoring the SWS. As integrated operating and programming interface, the RobotSyncUnit takes care of an optimised interaction of the robot, scanner and laser. Optional offline programming software allows simple import of CAD data.
