We have demo units available and look forward to your inquiries. Whether you are familiar with the previous LWM or are trying it for the first time, we encourage you to experience the latest LWM.

■ 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 IR lasers used in fiber transmission such as fiber lasers and disk lasers ■ Usable with medium power range lasers up to 6.6 kW ■ Compatible with a wide variety of laser cutting conditions from thin plates to thick plates ■ Available for 2D applications for flatbed processing machines and 3D applications for articulated robots ■ By using contour control devices, it is possible to maintain a constant distance from the workpiece to the nozzle ■ Capable of accommodating different materials and plate thicknesses with a focus position that can be adjusted dynamically and at high speed

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.

■ Monitoring of different molten materials such as aluminum and copper is possible through the principle of atomic inherent spectral line measurement. ■ The defect detection capability is enhanced by individual optical imaging of each channel of the LWM8.5 sensor. ■ The addition of a near-infrared channel enables monitoring in high-temperature processes. ■ By applying an inverse aperture during in-process review to the added temperature (infrared light) sensor waveform, monitoring of low-temperature processes is possible. ■ The LWM8.5 sensor does not require optical axis adjustment. A formal release is planned soon. We look forward to inquiries from customers. Whether you are familiar with the previous LWM or are trying it for the first time, please try the latest LWM4.0 and LWM8.5.

■ The main equipment configuration consists of only three components: a dedicated industrial compact PC, a sensor camera, and I/O communication devices. ■ Similar to the conventional WeldMaster, high-speed processing of measurements, inspections, and judgments suitable for the workpiece is performed according to customer requests. ■ Inspections using CLS are now possible, in addition to the sensor camera. <WeldMaster Sensor Camera> ■ The sensor camera has been completely renewed. It features a high-precision F64mm camera and an F120 camera that ensures a working distance. ■ By equipping the sensor camera with high-speed processing capabilities, parallel processing of 2D and 3D profiles has been dramatically accelerated. ■ Image inspection using grayscale images allows for accurate determination of the width and presence of the weld bead from the 2D profile. ■ By incorporating AI (machine learning) into image inspection, it is now possible to detect weld beads that were difficult to distinguish with previous equipment. <Color Aberration Confocal CLS Line Sensor> ■ Capable of acquiring 3D profiles of the work surface at the micron level. ■ Rapid detection of very small pits, cracks, shape changes, and more. We look forward to your inquiries.
