The invention discloses a dual
laser beam dual side simultaneous
welding wire filling droplet transfer
monitoring system and method based on high-speed photography. In the process of dual
laser beam dual side simultaneous
welding wire filling, a droplet
transfer mode and frequency are monitored in real-time by a high-speed camera
system, so that the purpose of monitoring dual
laser beam dual sidesynchronous
welding wire filling droplet transfer at different wire feeding speeds in the whole process is achieved. The dual laser beam dual side simultaneous welding wire filling droplet transfer
monitoring system mainly includes four parts of a duel laser beam duel side simultaneous welding wire filling
system, a high-speed video acquisition and
processing system, a full digital wire feeding
control system and an
image processing system, and is characterized in that the droplet transfer on both sides of a
stringer is monitored simultaneously by two high-speed cameras, and the acquired images are processed quickly by the
digital image processing software, so that the droplet transfer frequency is calculated quantitatively. According to the dual laser beam dual side simultaneous welding wire filling droplet transfer
monitoring system and method, the droplet
transfer mode and frequency can be monitored in real time, and thus the weld quality of laser welding is improved.
