Explosive cladding is also known as explosion welding. So, explosive cladding or explosive welding is the bonding of two dissimilar metals with the use of explosives. The explosive clad is achieved through a high-velocity oblique impact between two different metals.
The explosive cladding process
The high-velocity impact produces enough energy to dynamically hydrostream the impacting metal surfaces. The metal surfaces are compressed under high pressure from the explosion and an atomistic adhesion between the different metals will be achieved. This provides solid bonding.
Explosive cladding is a cold pressure weld process. This method is used to weld metals that can’t be welded by conventional processes. An example of two metals that can not be welded is aluminium-steel, a combination that is commonly used in shipbuilding. With Triclad, shipbuilders have a transition joint that welds aluminium to steel.
As the process uses a large quantity of specially produced explosive, the actual cladding operation is generally carried out in a remote place.
