本文对爆炸焊接铝板与铜板的焊接性及爆炸比对接头界面的影响进行了试验研究。实验结果表明，采用爆炸焊接方法可以实现铝与铜板的粘接。通过增大爆炸比对上板重量的影响，使接头界面由线形变为波纹状。此外，随着爆炸比的增加，波纹的波长和幅度也随之增大。硬度测量结果表明，冲击力使板材界面和外表面附近区域的硬度增加。爆炸焊接板经三点弯曲后，接头界面未见剥离现象。(C)2006爱思唯尔有限公司。保留所有权利。
In this study, weldability of aluminum sheet to copper sheet by explosive welding and the effect of explosive ratio on the joint interface have been investigated experimentally. Experimental results show that aluminium can be bonded to copper sheet by using explosive welding. The joint interface was transformed from linear to wavy appearance by increasing explosive ratio with respect to upper plate weight. Moreover, with increasing explosive ratio, the wavelength and amplitude of waviness increased. Hardness measurements indicate that the impact force leads to increase in hardness of the zone next to interface and outer surface of the plates. No separation was observed in the joint interface of explosively welded plates after three-point bending. (C) 2006 Elsevier Ltd. All rights reserved.
