SiC particle-reinforced aluminum matrix composites (SiC_p/Al) demonstrate broad application prospects in lightweight and large-scale aerospace equipments due to their high specific strength, low density, and low coefficient of thermal expansion. However, defects such as the formation of the brittle Al₄C₃ phase, porosity, and particle segregation readily occur during their fusion welding, severely restricting their engineering applications. Consequently, the demand for high-efficiency and reliable welding techniques is becoming increasingly urgent. This paper systematically reviews the research status of laser welding for aerospace SiC_p/Al from three aspects: conventional laser welding, external-fieldassisted laser welding, and laser welding with interlayers. Conventional laser welding (continuous, pulsed, or wobbling) can only optimize joint performance through process regulation, but cannot effectively suppress the formation of the brittle phase, and the process window remains narrow. External energy field assistance (arc, magnetic field, or ultrasonic) laser welding can effectively stabilize the molten pool, reduce macroscopic defects, and refine grains, yet it struggles to block the interfacial reaction. Interfacial reaction regulation laser welding, by introducing active elements to reconstruct the interfacial reaction path and transforming harmful phases into strengthening phases, has emerged as the key to achieving performance leaps. Finally, this review discusses the future research hotspots of the laser welding for SiC_p/Al composites, aiming to provide a reference for the large-scale and reliable welding of this material in the aerospace field.
