We will introduce a monitoring case of pure aluminum (t=0.3mm overlap welding).
We would like to introduce the usage examples of the laser welding monitoring device 'NAS-2000/3000'. In the monitoring examples, we detect holes caused by foreign matter contamination between samples. It is also possible to detect underfill that occurs when there is a gap between samples. Additionally, in the adaptive control examples, the laser output is controlled in real-time to maintain the thermal radiation intensity around 0.1. 【Overview of Monitoring Examples】 ■ When holes occur ・Laser power: 230W ・Welding speed: 8mm/s ■ When underfill occurs due to the influence of gaps ・Laser power: 230W ・Welding speed: 8mm/s *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Overview of Adaptive Control Examples】 ■Effects of Adaptive Control - By controlling the laser output to maintain a constant thermal radiation, stable melting widths can be achieved on both the surface and backside of the welding material. - The unstable region from the start of irradiation to saturation of melting can be reduced. *For more details, please refer to the PDF document or feel free to contact us.
