In this paper, the bonding ability of copper and aluminum with explosion welding was experimentally investigated using different ratio metal thicknesses.First of all, the scarf joint is described, then, all parameters of a table, named the weld ability window,
were calculated. Experimental studies showed that aluminum and copper plates were explosively welded; employing appropriate equations for the explosive loading ratio. The bond strength was investigated using special shear strength tests.According to shear test results, when the calculated values of minimum plate velocities along the interface were related to the locations in which separation appears, a proper relationship between the explosive loading ratio and the minimum plate velocity is obtained with a correlation factor.Consequently, the scarf joint not only provides a method of making a bond between dissimilar materials, but, also, is able to evaluate the main equations in the explosive welding process.
