This product is a monitoring system that continuously monitors the spatter generated during laser welding. The measurable features that can be monitored are the "number" of spatter flying out from the molten pool, the "scattering trajectory," and the "size." This allows for the acquisition of the spatter occurrence status during welding, demonstrating its effectiveness as a quality control support tool in mass production. Additionally, it can be effectively utilized for determining welding conditions in prototype and process development. 【Features】 ■ Automatic measurement of the number, scattering trajectory, and size of spatter ■ Real-time pass/fail judgment of the number and size of spatter ■ Visualization of the timing of spatter occurrence and all scattering trajectories *For more details, please refer to the PDF document or feel free to contact us.

During laser hardening, we monitor the surface temperature of the processing point and perform feedback control of the laser output to ensure that the heating temperature remains constant, achieving high-quality laser hardening. Additionally, we are equipped with a zoom homogenizer that allows for arbitrary adjustment of the beam size, enabling us to change the beam size programmatically during laser hardening to perform optimal laser hardening tailored to the workpiece shape and volume. 〇 Laser hardening using semiconductor lasers (18 minutes) https://www.youtube.com/watch?v=6Gm6Nf6PaXk

This is a technical service that visualizes and measures near-infrared lasers non-contactly. It enables the visualization of "focus shift" induced by the thermal lens effect due to the aging of optical components within the laser processing head, as well as the "beam diameter" and "Rayleigh length" of the focusing area. By visualizing the focusing state of near-infrared lasers, which cannot be recognized by the human eye, accurate judgments can be made. *For more details, please download the PDF or contact us.*

Marking and surface roughening processing is possible on various materials such as steel, SUS, aluminum, copper, resin, and wood. 【Roughening Treatment】 It is possible to create fine "indentations" or "dents" to increase the surface area. Surface roughness can be controlled, improving adhesion with resin. 【Dimple Processing】 It is possible to create extremely small depressions. This can serve as an oil reservoir, reducing friction in sliding parts. 【Grooving Processing】 It is possible to create clear "indentations" or "dents." This can also be used to improve adhesion with resin or as an oil reservoir. *For more details, please download the PDF or contact us.

"LEXA VIEW" is an in-process monitoring system that quantitatively captures the shape changes of the laser keyhole and the surrounding molten pool, allowing for continuous monitoring and comparative judgment to assess the quality of welding during the process. It can detect welding defects such as holes, underfill, penetration, non-penetration, and lack of fusion in butt joints and lap joints. Additionally, while not related to welding quality, it can also detect interference of the laser beam with the welding fixture. Please feel free to contact us if you have any inquiries. [Features] ■ Cost reduction by completing inspections simultaneously with welding ■ Utilizing accumulated data to detect trends and precursors of quality issues ■ Marking of defective areas during judgment *For more details, please download the PDF or contact us.
