Özet

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.
