Explosively welded Al/Cu clad is tried to be fabricated inserting Cu intermediate plate between Al driver and Cu base plates. In explosively welded Al/Cu clad using conventional method, generation of excess reacted interfacial zone caused the degradation of the bonding property. The use of Cu intermediate was effective as a mean of decreasing the energy dissipated by collision. The effect of kinetic energy lost by collision on the thickness of reacted interfacial zone and on the bonding strength were examined using small size experiments. Al/Cu electric transition joint with commercial size are tried to be fabricated by the use of Cu intermediate plate and the bonding property was fairly improved compared with it made by conventional method.
