Detection of weld dimension in open keyhole laser welding based on a CMOS coaxial visual sensing system;
基于同轴视觉传感的激光穿透焊接焊缝尺寸检测
By analysis of the keyhole, weld pool and plasma temperature character and electron density character, a coaxial visual sensing system was established to detect the optical emission of the keyhole and weld pool in deep penetration laser welding process.
