WebP is the shock pressure on the surface of explosive by flyer plate, τ is the duration of shock pressure, u is the particle velocity. The James criterion of the HNS-IV explosive can be expressed as follows given by Bowden et al. (Reference Bowden, Maisey and Knowles 2012) (${\rm \sum} _{\rm c} {\rm = 0}{\rm. 2042}$, E c = 0.0879) Explosion welding (EXW) is a solid state (solid-phase) process where welding is accomplished by accelerating one of the components at extremely high velocity through the use of chemical explosives. This process is often used to clad carbon steel or aluminium plate with a thin layer of a harder or more corrosion-resistant material (e.g., stainless steel, nickel alloy, titanium, or zirconium).
