■ A scanner optical system equipped with all functions for tracking, monitoring, and inspection. ■ All functions are consolidated into a single control device, making control from the PLC easy. ■ All settings, editing, and management can be performed through a GUI displayed on a single monitor, making operation easy. ■ Since ScanMaster controls all functions during processing, communication time for control from the PLC is reduced, significantly shortening processing time. ■ Not only XYZ correction but also control of welding trajectories and laser power based on the workpiece's gap, steps, and shape, aiming for zero welding defects. <Representative functions equipped in ScanMaster> - 2D scanner enabling dynamic processing - Motor-driven collimator for high-precision adjustment of laser focus - OCT for accurately measuring the height of the workpiece - LPM sensor for measuring laser power passing through the processing head - LWM for assessing processing quality during laser welding using plasma, temperature, and reflected light - Sensor camera for accurately detecting welding points through images - Light to brightly illuminate the workpiece and cross jet to prevent spatter adhesion

■ For fiber transmission lasers such as fiber lasers, disk lasers, and LD lasers ■ Usable with lasers up to 6kW ■ Since the wire and laser come out coaxially, there is a wide Z-axis processing allowance ■ The wire is always supplied from the center axis of the laser, eliminating the need for delicate adjustments between the wire, laser, and workpiece ■ The laser preheats the wire, improving the shaping speed ■ Temperature monitoring with a pyrometer allows for laser power control and heat input management ■ Height monitoring before and after buildup with OCT controls wire supply and laser power for shape management

High-quality laser welding of copper and aluminum is essential for e-mobility applications. Despite the challenges posed by these highly reflective and thermally conductive materials, achieving precise welding results is crucial for optimal conductivity and stable circuits. In collaboration with Cailabs, we provide innovative beam shaping solutions that enhance laser interaction with these materials. By using beam shaping technology, the laser output is divided into points and rings, allowing for an even distribution of laser output. Due to the low thermal load, the seams become more homogeneous, and the amount of spatter is significantly reduced. This system is easy to implement, as all optical components are integrated, ensuring long-term stability, reliability, and maintenance-free operation. All components enable the use of high laser output through a fully reflective design and optimized cooling, guaranteeing a stable process. Additionally, an online quality management system can also be integrated.

The coaxial wire supply method laser cladding welding "CoaxPrinter" is a laser cutting head capable of handling a wide range of applications in additive manufacturing, from filigree structures to complex shapes and designs. It can be used for 3D printing, prototype manufacturing, and protection against wear, achieving uniform cladding quality that is independent of direction. 【Features】 ■ Coaxial laser processing head that focuses a ring-shaped laser around the wire ■ No need for alignment between the wire and laser... reduces labor for skilled technicians ■ The head is slim, with no restrictions on welding direction... non-directional processing ■ Reduces waste of wire that was previously discarded during alignment... lowers material costs ■ Eliminates leftover wire at the end of welding, so there is no need to cut the wire with nippers after each processing... reduces workforce ■ The wide tolerance in the Z direction makes it less likely for processing defects due to focal shift... reduces defective products ■ The approaching laser focuses on the wire, warming it before processing... dramatically increases processing speed *For more details, please download the PDF or contact us directly.

This is a contour control device for Precitec cutting heads. It integrates the "EG8010," "EG8030," or "EG8050" contour sensor amplifiers and the "I/O board" for laser focus position control into a single unit. The GUI functionality, which can be operated via a web browser, allows for easy management and monitoring of the head's status. The BeamTech function automatically corrects the laser focus position to mitigate the adverse effects of thermal focus shift phenomena, which are a major concern in high-power laser cutting, enabling cutting at the correct laser focus at all times. Communication between the NC or PLC and the CutBox will be via bus control communication using EtherCAT or ProfiNet. Unlike digital I/O, it allows for the exchange of multiple pieces of information.
