The specific features of explosive cladding of St. 3-steel plates and shell
s by copper and aluminum foils of thickness 20 and 50 mu m are investigated
. It is shown that the cladding is reliable if the foil thickness is compar
able with the height of microroughness of a clad surface. The quality of th
e joint is worsened when the degree of surface finish is improved. The qual
ity of the joint can be improved if the duration of loading is increased. T
he microroughness of the surface decreases during cladding.
