Özet

In this study, AISI 430 and S235JR plates were joined via explosion welding method, which is one of solid state welding methods, and by using two different explosive rates (R=1,5-2). Microstructure, hardness, and fatigue tests were carried out in order to see changes occurring in the joint interfaces of the materials obtained after joining processes and to determine their mechanical properties. As a result of the microstructure studies made, it was observed that there was very little fluctuation at the interface between the two samples, but at the sample interface where higher explosive ratio was used, it was found that there was a slight increase in the length and amplitude of the generated waves. An increase was determined in hardness of materials joined due to deformation occurring as a result of increase of explosive rate. In fatigue tests applied to joined plates, a decrease was found in fatigue life of the joined plates as a result of increase of explosive rate.
