OPTICAL POWER ATTENUATION ADJUSTMENT SYSTEM AND METHOD, AND LASER WELDING SYSTEM

WIPO Patent Application WO/2020/173209

A1

An optical power attenuation adjustment system (300) and method, and a laser welding system, for use in the field of lasers. The optical power attenuation adjustment system (300) comprises an optical power attenuation control apparatus (10) and an optical power attenuation apparatus (20), the optical power attenuation control apparatus (10) comprising a processor (11) and a light intensity sensor (15) and a drive module (16) respectively electrically connected to the processor (11), the drive module (16) being electrically connected to the optical power attenuation apparatus (20); the harm to the laser (100) and the QBH collimation system (200) caused by reflected light during high-power welding is thereby avoided, increasing the overall safety of laser welding.
