介绍了感应钎焊技术在雷达产品常用钎焊铝合金上的应用,通过对铝合金感应加热的感应器优化设计技术和精密温控技术的研究,实现了铝合金感应钎焊的精密控温,进行了管与管、管与法兰异型接头的感应器设计,开展了铝合金的感应硬钎焊工艺研究,分析了铝合金感应钎焊工件的钎焊缝和钎焊圆角、尺寸变形精度、表面氧化和微观组织等。文中实现了铝合金复杂结构的感应钎焊,并应用于铝合金6063法兰和3A21方型波导管接头的钎焊,为此类结构提供一种新的焊接方法。
The application of induction brazing to aluminum alloy composite in radar was introduced.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.
