对铝-铝同质金属爆炸焊接进行系列实验，研究不同装药比条件下焊接界面的变化特征。

A series of Al-Al explosive welding experiments were carried out to investigate the morphology characters of welding interface under the condition of different charge ratios.

随装药比的增大，马赫孔从有到无，但当装药比继续变大时，则会再次出现马赫孔且有增大的倾向；

With the increase of the ratio the density of the sample increases at first and then decreases when the ratio reaches certain critical value and the mach pore is decrescent at first and later largens.

结果表明：随着药型罩曲率半径、装药长径比、壳体厚度的增大以及药型罩壁厚减少，EFP的速度增大。

It shows that with the increasing of curvature radius, liner thickness, the length-to-diameter ratio of the charge, and decreasing of shell thickness, the velocity of EFP increase.
