Development of a Mathematical Model in Prediction of Shear Strength in Cladding Materials by Scarf Explosive Welding of Aluminium to Copper Plates

In Explosive Welding (EXW) process, there is a situation in which high amount of pressure in collision point leads to decrease in impurity of superficial layers and metal gets in contact with another dissimilar metal and Metallurgical bond can be initiated at the interface. In this paper, in addition to introduction of scarf welding, explosive welding of aluminium to copper plate in different conditions of explosive loading performed and shear strength of bond was evaluated through new method. The Relationship between shear strength and explosive loading was demonstrated by establishment of non-linear and logarithmic models through regression method and ANOVA table. Adequacy of the developed models was verified in explosive cladding process. Consequently, explosive loading varieties can be evaluated in one experiment by production of scarf joint between dissimilar metals (according to the computational method employed in this paper) and with development of proper model, the shear strength of cladding metals can be estimated.
