Scanner Welding System

Share this on social media:

Rofin’s Scanner Welding System (SWS) is a fast beam deflection system used for robot-guided multi-spot welding and developed for use in conjunction with Rofin’s fibre laser series, which is available with output powers of up to 4,000W.

The fibre laser can be integrated into fully automated welding systems, in combination with a 3D scanner and the RobotSyncUnit. The flexibility of SWS enables complex 3D components to be welded. By combining the axes of the scanner with those of the robot as the presentation mechanism, the system commands a total of nine selectable axes.

Regardless of weld type, spot, circular, wave or stitched seam, the seam geometry is freely programmable and can therefore be configured to specific strength and component requirements. The high-speed rotating mirrors in the scanner head allow extremely fast positioning of the laser beam, in the millisecond range, across the working field. The robot’s movements and speeds can also be optimised using optional offline programming. These features minimise the non-productive time between weld positions to provide high process utilisation.
