爆炸焊接两板间距上限法则分析与试验

为了研究两板间距参数与装药厚度之间的关系及其对爆炸焊接界面质量的影响规律，通过分析复板在基复板间距内运动规律，建立与间距相关的复板运动模型，进而确立了复板运动速度与间距之间的变化规律，提出爆炸焊接两板间距参数应遵循上限法则. 根据该间距上限法则，对304/Q235B进行了四组爆炸焊接间距试验以及相应的微观界面测试. 结果表明,上限间距参数不仅能获得良好的焊接界面，而且由于能充分利用炸药的能量而使得所用的装药厚度降到最低.

Analysis and experiment on upper limit law of two plates stands in explosive welding

To study the relationship between two plates stands and explosive charge thickness and the effect on the bonding interface quality of explosive welding, the movement model of the flyer plate stands is established and the variety regularity between velocity of flyer plate and two plates stands is obtained by analyzing the movement regularity of flyer plate in the stands. The upper limit law of stands parameters is put forward on explosive welding. According to the law, four groups of 304/Q235B explosive welding experiments are carried out. The results indicates that the good welding interfaces are gained by using the upper limit stands parameters, meanwhile it is observed that the explosive charge energy can be saved greatly by the micro interface tests.
