Abstract: SiC_p/Al composites are widely used in the aerospace field due to their excellent properties, but due to the difference in thermolhysical properties between Si C reinforcement and aluminum matrix, problems such as welding defects and reinforcement phase segregation are likely to occur, which can affect the quality of the welded joint. The research progress of direct laser welding, field-assisted laser welding and interfacial in-situ reaction laser welding was reviewed.
