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). Due to the nat…
WebMar 23, 2024 · Here \(r\) is the ratio of the explosive mass to the mass of the flyer plate, \(k\) is the adiabatic index of the explosion products behind the detonation front, and \(y\) is the ratio of the welding gap between the plates to the thickness of the explosive charge. The values of \(k\) for different explosives are known. In particular, for the used 50/50 …
