AI Technical Summary
Existing technologies are prone to defects such as porosity and cracks in the laser welding of light alloys. Furthermore, the optimization of welding processes is time-consuming and labor-intensive, and the cost of post-weld quality inspection is high. There is a lack of intelligent laser powder filling welding devices and methods.
An intelligent laser powder-filling welding device and method based on multi-sensor online monitoring is adopted. The welding process is monitored in real time by a line laser measuring instrument, a spectrometer, a high-speed camera and an infrared thermometer. The control system adjusts the powder feeding amount and welding process parameters to realize the reconstruction of the three-dimensional model of the weld and the optimization of the post-weld quality prediction model.
It improves welding quality and efficiency, reduces post-weld quality inspection costs, and enables rapid, accurate, and automated welding of workpieces of different materials and sizes.
