An Investigation on Explosive Welding of Bimetallic Ribbed Panel

In this study, a 316L stainless steel sheet and Q345R steel ribs are cladded to be a bimetallic ribbed panel which is hardly be manufactured by normal processing technique. There are three key sections in the fabrication process: the parallel arrangement, optimization of the explosive welding parameter and the template filling and stripping. The bonding interfaces of the ribbed panel are observed and analyzed by means of mechanical test and optical microscope (OM). It is found that welding interface is wavy, and the bonding strength is higher than that of base plate.
