| The work aims to realize Al/Cu connection by large-area brazing and analyze the microstructure and properties of 6063Al/Cu welded joint with 4104 aluminum foil as the intermediate layer respectively, thus obtaining the welding process with excellent mechanical properties. The microstructure of the joint was analyzed by SEM and EDS, and the effects of holding time and pressure on the microstructure and properties of the joint were studied. The fracture characteristics and mechanical properties of the joint were studied by shear test, and the optimal welding process was determined. The maximum shear strength of 6063/Cu joint was greater than that of 6063Al/4104Al/Cu joint. When the welding temperature was 540 ℃, the holding time was 10 min and the pressure was 600 Pa, the best mechanical properties of 6063Al/4104Al/Cu joint were obtained, and the shear strength of the joint was 48.8 MPa. Welding temperature, holding time and pressure are very important for large-area aluminum-copper welding. The 4104 aluminum foil as intermediate layer metal can realize good connection between 6063 aluminum alloy and copper. |
