RLW-S

Scansonic’s new SCW (Safe Component Welding) laser welding optic enables laser welding without a protective cell. The compact processing unit meets Class 1 laser requirements, saving significant investment costs and offering new flexibility for production use. The focus is on a specially developed protective attachment mounted on the optic. A form nozzle encloses the welding area, preventing the escape of dangerous laser radiation. It is customized to the geometry of each workpiece, ensuring reliable protection for operators without additional housing. Only a simple robot protection cell is needed, significantly reducing overall costs compared to traditional laser welding systems. Proven Technology – Now Even Safer The new welding optic is based on Scansonic’s proven FCW system, which uses high-precision 3D scanner technology for accurate welding processes. An integrated image recognition system covers a working area of 5 x 25 mm, allowing users to securely determine the welding position using a teach-in procedure. A promising application is the fixation of the inner door part to the outer part after folding in body construction. The adhesive in the folded connection cures only during painting. Until then, additional fixation points are necessary, which can be welded with the SCW system. Double Security: Integrated Safety Technology A key element is the comprehensive safety system: redundant sensors continuously measure the distance between the workpiece and the form nozzle. If the limit of 0.2 mm is exceeded, the beam source is not released. The solution meets all requirements for industrial series production. The new SCW optic is available as a fully integrated solution – including control (with safety components), laser source from Brightlight Laser, cooling, and extraction. Customers benefit from a coordinated system that significantly reduces engineering effort. | The RLW-S enables automatic recognition of patterns on the component as well as the position of the laser beam relative to the pattern contour. This makes it possible to define specific welding paths. A camera positioned coaxially to the laser beam detects the pattern layer(s). The movement of the laser beam is then calculated and executed via the path planning according to the parameterization. The deflection of the laser beam takes place via highly dynamic scanner axes and allows a positioning on the component along with a manipulation of the heat input via oscillation movements.
