Scansonic presents a new welding optics at the Laser – World of Photonics in Hall 3 that meets the requirements of Laser Class 1. This eliminates the need for a complex and costly laser safety cell.

With its new SCW (Safe Component Welding) laser welding optics, Scansonic enables laser welding without a laser protection cell, as the company emphasizes. This is because the compact processing unit meets the requirements of laser class 1, which not only saves high investment costs but also creates new scope for flexible laser use in production. The focus is on a specially developed protective attachment that is attached to the laser welding optics. A so-called shaped nozzle encloses the welding area and prevents laser radiation that is harmful to the eyes from penetrating to the outside. It is individually adapted to the geometry of the respective workpiece. This means that the operating personnel are reliably protected at all times - without any additional enclosure. All that is needed is a simple robot protection cell, which reduces the overall costs compared to conventional laser welding systems.

Door Production is supported by Laser System

According to Scansonic, the new welding optics are based on the already established FCW system, which uses precise 3D scanning technology to ensure exact welding processes. Integrated image recognition covers a working area of 5 × 25 millimetres, so that the user can use teaching to reliably define the position at which welding is to take place. One promising application is therefore the fixing of inner door parts to outer parts after folding in the shell construction phase. This is because the adhesive in the folded joint only hardens in the painting unit, as Scansonic explains. Additional fixing points are therefore required up to this point, which are then welded using the SCW system.

Fully Integrated Laser Welding System Makes it Easier

A central element is the comprehensive safety system, as the company explains further. A redundant sensor system continuously measures the distance between the workpiece and the forming nozzle. If the limit value of 0.2 millimeters is exceeded, the laser beam source is not released by the system. This function meets all the requirements of industrial series production. The new SCW optics are also available as a fully integrated system - including control (with safety components), laser source from Brightlight Laser as well as cooling and extraction. Laser users benefit from a coordinated system that significantly reduces engineering costs.
