摘要(Abstract)：

针对爆炸焊接参数设计问题,从爆炸焊接基本理论出发,分步介绍了飞板爆轰驱动的理论和双金属爆炸焊接窗口理论。首先归纳总结了一维爆轰驱动飞板的终速公式,并详细说明了其应用范围与原因。对于二维滑移爆轰驱动飞板问题,主要针对Richter理论和特征线法进行了介绍,并推导出新的近似计算公式。接着,对于爆炸焊接参数窗口理论,详细比较了以往传统单一金属爆炸焊接窗口理论与公式,并针对部分已有公式进行了重新推导与修正,重新界定了其适用范围。利用这些爆炸焊接窗口的基本理论,作者对所发展的双金属可焊下限、双金属可焊上限、双金属流动限以及声速限构成的双金属爆炸焊接窗口理论进行了系统地介绍。最后,以飞板爆轰驱动和爆炸焊接窗口构建成了整个爆炸焊接工艺技术参数设计理论,并结合二元合金相图进行爆炸焊接设计,针对调控原材料硬度的必要性、焊接界面波纹及气孔的控制方法等问题进行了讨论。
Aiming at parameter design of explosive welding, the theory of detonation driving flyer and bimetal explosive welding window are introduced step by step based on the basic theory of explosive welding. First, the ultimate velocity formula of one dimensional detonation driven flyer plate is summarized, and its able range and reasons are explained in detail. Furthermore, Richter theory and characteristic method are mainly introduced for the problem of flyer driven by two-dimensional grazing detonation, and a new approximate calculation formula is derived also. Then, for the theory of explosive welding parameter window, the traditional single metal explosive welding window theory and formula are compared in detail, and some existing formulas are re-deduced and modified, and its application scope is defined again. Based on these basic theories of explosive welding windows, the author systematically introduced the theory of bimetal explosive welding window, which is composed of bimetal welding lower limit, bimetal welding upper limit, bimetal flow limit and sonic limit. Finally, the whole design theory of explosive welding process parameters is built up with detonation driven flyer and explosive welding window. In addition, explosive welding design based on binary alloy phase diagram, the necessity of controlling the hardness of processed metals, the method of controlling waves and pore defects of welding interface are briefly discussed.
