The ROFIN Laser MACRO Group is setting new benchmarks in the area of remote welding with the RWSflex. With a new control unit from ABB and more flexible programming, the high-speed welding system opens up new possibilities for creating laser-stepwelding of any geometry.

Due to the extended operating distance, RWSflex offers a larger working area of 1450 mm x 3200 mm x 700 mm. This is based on a focal length of 1600 mm. System dynamics have been optimised as well to further decrease unproductive welding downtime.

Further highlights of the RWSflex are its offline programming capability, which ensures more flexible work preparation, as well as the freely programmable position of the exit window of the laser beam. The cover of the traversing path protects the beam control unit against the laser beam reflections and welding spatter from the process.

“RWSflex is a natural development of our RWS Technology in the market, which has been highly successful for many years. With a new control unit from ABB, offline programming capability and improved system properties, we have consistently aimed at meeting our customers’ requirements“, reports Thorsten Frauenpreiß, Managing Director of Rofin-Sinar Laser GmbH. “We are satisfied at having been able to set a new milestone in Remote Technology with RWSflex and to develop new areas of application“.

RWSflex is operated with CO2 Slab lasers from ROFIN’s patented DC Series. These lasers are the ideal tools for this demanding application, with an excellent beam quality of K ? 0.9. All lasers of the DC product family have a perfect fundamental mode structure and thus contribute to ensuring the best conditions for high-speed welding with high focal lengths. Optionally, solid-state lasers with high beam qualities could be used.
