摘　　要：针对双立式爆炸焊接新方法的爆轰驱动特点,通过研究双立式爆炸焊接条件下的焊接下限、焊接上限、临界起爆厚度、临界碰撞角和临界复板厚度等可焊性边界条件,构建了一种静态参数下的双立式爆炸焊接R-δ型可焊性窗口;该窗口综合反映了爆炸焊接中的复板特性和炸药特性两大焊接参数,所建立的铜、不锈钢、铝合金等材料的双立式爆炸焊接R-δ型可焊性窗口可直接运用于工程实践中;根据双立式爆炸焊接R-δ型可焊性窗口设置的15 mm超低药量试验下的304L/Q235b复合板实现了高质量的微小波状结合,说明该窗口可以作为确定双立式爆炸焊接工艺参数的依据.Based on the detonation characteristics in anew double vertical explosive welding process,the R-δ-Type weldability window of double vertical explosive welding with static parameters is established,by studying the boundary conditions including,lower limit,upper limit,critical initiation thickness,critical collision angle,the critical plate thickness,etc. The R-δ-type weldability window reflects the relevance between the material properties and explosive characteristics,which are the two most important welding parameters of explosive welding. The R-δ-type weldability window for copper,stainless steel,aluminum and other materials can be directly utilized in engineering practice. A welding experiment between 304 L and Q235 b has been done with the ultra-low charge of 15 millimeter thickness based on the R-δ-type weldability window for double vertical explosive welding. The bonding quality of 304 L / Q235 b composites after welding is good with small wavy combination on the interfaces,which indicates that the proposed window can be used to determine the process parameters of double vertical explosive welding.
