针对实际生产中在爆炸焊接窗口内取值时因为所取参数不同而导致生产的复合板结合强度差异较大这一现状，通过对SUS304不锈钢/Q345R碳钢爆炸焊接窗口内不同工艺条件得到的复合板进行剪切强度测试及金相分析，得到界面结合强度与界面波形的关系以及两者随工艺参数的变化规律，找到窗口内最佳的工艺参数，以提高爆炸焊接复合板质量以及生产效益。研究表明：界面波形的波长和振幅随着装药量的增加而增大，随基复板间距的增加先增大后减小。爆炸焊接窗口内最佳工艺参数取值范围与复板厚度有关。复板为薄板(3 mm)时，取得最佳结合强度时界面波形波长为1250 μm左右，振幅为200 μm左右，对应的最佳装药质量比为1.02，基复板间距为8 mm，取值比理论最佳值偏高；复板为厚板(6 mm)时，取得最佳结合强度时界面波形波长为900 μm左右，振幅为100 μm左右，对应的最佳装药质量比为0.45，基复板间距为14 mm，取值靠近下限。当界面波长与振幅相同时，复板为薄板的结合强度要高于厚板。

In practice the situation of different parameters in the explosive welding window gives rise to a significant difference of bonding strength. The shear strength test and the metallographic analysis of clad plate were obtained by different processes of SUS304 stainless steel/Q345R carbon steel explosive welding window. As results, the relationship between interfacial strength and waveform, and the mechanism of the above two changing with the process parameters can be deduced as well as the best process of stainless steel/carbon steel explosive welding. It shows that wavelength and amplitude increase with the increase of charge quantity, and increase at first and then decrease with the increase of the distance between flyer plate and base plate. The best process parameters in the explosive welding window are dependent on the thickness of flyer plate. The wavelength is about 1250μm and amplitude is about 200μm, resulting in the best bonding strength when the flyer plate is thin (3mm). The corresponding mass ratio is 1.02, and the distance between flyer plate and base plate is 8mm, which is higher than the theoretical best parameters. The wavelength is about 900μm and amplitude is about 100μm, which results in the best bonding strength when the flyer plate is thick (6mm). The corresponding mass ratio is 0.45, and distance between flyer plate and base plate is 14mm, which is close to lower limit. The bonding strength of thin flyer plate is higher than that of thick flyer plate, when their wavelength and amplitude are same.
