Abstract
Explosion welding is a solid-state process that produces a high velocity interaction of dissimilar metals by a controlled detonation.Oxides found on material surfaces must be removed by effacement or dispersion.Surface atoms of two joining metals must come into intimate contact to achieve metallic bond.Cladder metal can be placed parallel or inclined to the base plate.Explosive material is distributed over top of cladder metal.Upon detonation, cladder plate collides with base plate to form weld.welding is accomplished by accelerating one of the components at extremely high velocity through the use of chemical explosives. This process is most commonly utilized to clad carbonsteel plate with a thin layer of corrosion resistant material (e.g., stainlesssteel, nickel alloy, titanium, or zirconium). Due to the nature of this process, producible geometries are very limited. They must be simple. Typical geometries produced include plates, tubing and tube sheets.
