Abstract

The 6063 Aluminum alloy brazing joint was prepared with the Al-Si12 solder. The effect of brazing temperature on the microstructure and shear properties of the brazed seam was studied and the interface was analyzed. With the increase of welding temperature, the shear strength of 6063 aluminum alloy joints first increases and then decreases with the increase of brazing temperature. When the optimal brazing process is 605℃ for 15 min, the interface between Al-Si12 solder and aluminum alloy is good, and the shear strength is 126 MPa. The fracture form of the joint is brittle fracture. In order to ensure the bonding strength of 6063 aluminum alloy, the optimal welding temperature for brazing is 605℃.
