摘要
为了获得焊接后性能稳定的多层金属板,该文通过调节金属板层间间距和添加撞击板,对七层和十一层铝板进行了爆炸焊接研究。将层合材料进行切割分析,由结合界面的显微金相照片可知块体焊接质量良好;显微硬度分析表明,材料结合界面附近区域硬度有所增加且各界面处硬度波动不大,证明各层的相互撞击速度基本一致。该文研究结果为控制层间撞击速度,使其达到基本一致,且接近焊接下限提供了解决方法。
In order to obtain the muhilayer metal plates with stable property after welding, the spaces between two metal plates are regulated, an impact plate is added, and the explosive welding experiment on the seven-layer and eleven-layer aluminum plates are done. The muhilayer plates are cut and analyzed. The metallographs of the bonding interfaces show that the bonding wave is small and good. The micro-hardness analysis indicates that the hardness near the interface is higher and each welding interface is approximate, concluding that the impact velocity of each layer is similar. The results provide a solution to the problems of how to control the impact velocity and how to make the impact velocity for each layer approximately equal and close to the inferior limit in the explosive welding of muhilayer metal plates.
