AI Technical Summary
Existing laser welding technology is prone to quality problems such as incomplete melting of the welding wire, rough weld surface, porosity and cracks in the final stage of welding. In particular, the end of the welding wire adheres to the semi-solidified molten pool, forming a spherical protrusion or crack at the end.
By obtaining the preset wire feeding speed of the welding wire during the laser welding cycle, the corresponding power reduction period for the shutdown phase is determined. Based on this period and the wire feeding speed, the wire speed reduction parameter and power reduction parameter are set to control the laser and the wire feeder to gradually reduce the laser power and wire feeding speed during the power reduction period, so as to achieve coordinated reduction.
This ensures that the welding wire is gradually melted as the laser power decreases, preventing the wire ends from sticking together and improving welding quality and efficiency.
