Subject Terms: *Explosive welding, *Interface structures, *Mechanical behavior of materials, *Impact (Mechanics), *Welded joints, *Dissimilar welding, *Weldability
Abstract: This review analyzes the influence of loading ratio, a principle process parameter in explosive welding, on the interface morphology, and mechanical properties of similar/dissimilar joints. The loading ratio (weight of the explosive mass/weight of the flyer plate), dictates the collision velocity, dynamic bend angle, and jet formation. It influences the nature of interface—straight, wavy, or intermetallic layer formation—thereby impacting the weldability of dissimilar metals. The judicial selection of loading ratios ensures good welding with minimal defects, while excessive or insufficient loading ratios lead to incomplete bonding or interface degradation. This article summarizes the key experimental findings and offers insights for process optimization and future research directions. [ABSTRACT FROM AUTHOR]
