摘　　要：爆炸焊接界面附近温升是由爆炸绝热压缩和畸形变形能沉积两者造成的。通过计算绝热压缩温升和畸形变形能沉积产生的温升,给出熔化判据,估计出了不同碰撞角下爆炸焊接界面熔化层厚度。Temperature rising near explosive welding interface is caused by explosive adiabatic compression and sedimentary abnormality deformation energy. Through the calculation of temperature rising caused by adiabatic compression and sedimentary abnormality deformation, melting criterion is given, the thickness of melted layer near explosive welding interface with different collision angle is estimated.
