Development of Weldability Window for Aluminum-Steel Explosive Cladding

Abstract

This study addresses the development of biaxial and triaxial weldability windowan analytical estimation-for determining the nature of interface in aluminum 5052-stainless steel 304 dissimilar explosive cladding. The lower and upper boundaries of the biaxial weldability window are formulated using empirical relations proposed by earlier researchers. The process parameters dynamic bend angle and collision velocity are chosen as ordinates and abscissa respectively. In addition, a triaxial weldability window, comprising of three process parameters viz., flyer plate velocity, collision velocity and dynamic bend angle is also developed. Explosive cladding experiments were conducted by varying the process parameters and the interface microstructure is correlated with the developed weldability windows.
