A hydrodynamic model of explosive welding is considered. A swinging wake model for explosive welding is used to explain the generation of interfacial waves and to predict wave characteristics. The two plates are considered as main fluid jets divided by stagnation streamlines into a saliant jet and a reentrant jet. The model considers that the wake swings from side to side behind an imaginary obstacle bounded by the stagnation streamlines, thereby producing a wavy interface. Prediction of degree of distortion, η, and amplitude-to-wavelength ratio h/λ, by the swinging wake model show reasonable agreement with the available experimental results. The expression for the diameter of the obstacle is developed for the general situation in explosive welding.
