为解决传统爆炸焊接中能量利用率和工作效率较低的问题，提出了一种多层爆炸焊接新方法.以五层爆炸焊接为例，304不锈钢板和Q235钢板分别作为复板和基板，进行了多层爆炸焊接和传统单层爆炸焊接的对比试验，并对爆炸焊接窗口和复板碰撞速度进行了理论计算. 结果表明，与传统爆炸焊接技术相比，五层爆炸焊接中可节省炸药量63%，并且五层爆炸焊接技术通过一次爆炸作业可获得五块焊接板，有利于提高爆炸焊接作业的工作效率. 此外，得到了304不锈钢和Q235钢的爆炸焊接窗口并对结合质量进行了预测，试验和预测结果吻合良好.

In order to solve the problem of low energy efficiency and low work efficiency in existing explosive welding, a new multi-layer explosive welding technology was proposed. In the case of five-layer explosive welding, 304 stainless steel and Q235 steel were used for flyer plate and base plate respectively. Comparison tests of multi-layer explosive welding and existing single-layer explosive welding were carried out. The explosive welding window and the impact velocity of the flyer plate were calculated theoretically. The result showed that energy utilization of the five-layer explosive welding increased by 63% compared to the existing explosive welding technology, and the five-layer explosive welding technology obtained five welded plates through one shot, which improved the working efficiency of the explosive welding. In addition, the explosive welding window of SUS304/Q235 was obtained and the welding quality was predicted, the experiment and prediction were in good agreement.
