The application discloses a kind of wide slit
thick plate laser welding intelligent control systems, belong to
laser welding technical field, including
perception module, control module, execution module and self-adapting pad module.
Perception module obtains weld geometry,
molten pool image and temperature
field data in real time by three-dimensional
laser vision, high-speed camera and
infrared thermal imager;Control module utilizes
deep learning network to carry out weld three-dimensional reconstruction and volume calculation, and predicts wire feeding speed through
hybrid neural
network model, while using proximal strategy optimization
algorithm to adjust laser power,
welding speed and swing parameter in coordination;Execution mechanism module executes welding action;Self-adapting pad module realizes
molten pool reliable support and automatic separation by heat-sensitive release
coating and electromagnetic lifting.The present application solves the problems of insufficient spot coverage, inaccurate wire filling, unstable process and pad adhesion in wide slit
thick plate laser welding, significantly improves welding quality and efficiency, and has data closed-loop self-evolution ability.
