The Effect of Explosıve Ratıo on Interface Formatıon in Explosıon Weldıng of Non Alloyed and Austenıtıc Steel Plates

Abstract

In this study, weldability of austenitic stainless steel sheet to DKP sheet metals by explosive welding and the effect of explosive ratio (Elbar 5) on the joint interface have been investigated experimentally. Experimental results show that austenitic stainless steel can be bonded to DKP sheet by using explosive bonding. The joint interface was transformed from line ar to wavy appearance within increasing explosive ratio with respect to upper plate weight. Moreover, with increasing explosive ratio, the wavelength and amplitude of waviness increased. Hardness measure indicate that the impact force leads to increase in hardness of the zone next to interface and outer surface of the plates.
