The present invention relates to a laser repair system and method based on light alloy powder preheating, the system includes a fixed support structure, a laser light source, a preheating extrusion mechanism, and a powder feeding mechanism. After receiving the surface damage data of the structural part, the intelligent control host intelligently identifies the damaged area of ​​the structural part, slices it in layers, and plans the repair path and preliminary process parameters. At the same time, the powder feeding mechanism and the induction preheating device are controlled to heat and melt the required light alloy powder before the repair process begins, and the damaged area is repaired in conjunction with the laser heat source. Subsequently, the induction heating power is reduced and the laser power is increased, so as to achieve the purpose of improving the powder utilization rate in the laser repair process and improving the surface repair quality of the structural part. The present invention provides a solution for preheating powder consumables before the laser repair process begins, which effectively improves the adhesion of metal consumables on the surface of the damaged area, and provides technical support for improving the powder utilization rate in the laser repair process.
