Abstract

The invention discloses an aluminum alloy welding method based on a SiCp / Al composite strengthening mechanism and belongs to the technical field of aluminum alloy welding. By means of the method, on the basis that a conventional welding method is used for welding an aluminum alloy, a synchronous powder sending manner is used for evenly adding SiCp into a molten pool at the same time, and a weldingconnector with a SiCp / Al composite as the main part is formed; and the SiCp / Al composite strengthening mechanism is utilized, the added SiCp can cause lattice deformation of base metal, the dislocation density is improved, in addition, the SiCp has high hardness and wear resistance, the welding connector softening problem happening when the conventional welding method is used for welding the aluminum alloy can be solved, and the welding connector can have high strength, hardness and good wear resistance.
