Explosion welding

Explosion welding:

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.

Principle of Explosion:-

>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.

Advantages:-

>No heat-affected zone (HAZ)
>Only minor melting
>Material melting temperatures and coefficients of thermal expansion differences do not affect the final product

Applications:-

>Any metal with sufficient strength and ductility can be joined
>Can weld large areas of metal
>Can weld inside and outside surfaces of pipes
>Transition joints can be made
