Abstract

Commercially pure titanium and 304 stainless steel were welded using explosive welding technique. The joints were evaluated using optical microscope, scanning electron microscope, energy dispersive spectroscopy and X-ray diffraction. The study indicates the formation of characteristic interfacial oscillations with vortices at high energetic conditions. The reacted products of the vortices have been identified as FeTi and Fe2Ti intermetallics by X-ray diffraction. Increase in the kinetic energy spent at the interface cause the volume of vortices to increase. Smooth wavy and flat topography has been obtained for thin flyer plates due to less kinetic energy loss. The results demonstrate a good welding interface for multi-layered welding using a thin stainless steel interlayer, as the kinetic energy dissipation at the interface was less.
