The induction brazing temperature was precisely controlled by the optimization of induction coil and the research on temperature - control technology. The induction coil used in brazing tube/tube or tube/flange joint was design, and the induction brazing process was also studied. The brazed joint, brazing deformation, surface oxidation, and microstructure of the aluminum alloy were analyzed. This study realizes the induction brazing of aluminum alloy composite with complicate structure, and this technology was applied to braze 6063 aluminum alloy flange and 3A21 aluminum alloy rectangle wave guide, which provided a new method to braze aluminum alloy composite with similar structure.
