Another common process, explosion welding, involves the joining of materials by pushing them together under extremely high pressure.

The welding mechanism is most similar to that in explosion welding.

Explosion welding can produce a bond between two metals that cannot necessarily be welded by conventional means.

Explosion welding is therefore far less commonly used than fusion welding alternatives.

Open-faced sandwich configurations are used in Explosion welding and some other metalforming operations.

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.

Unlike other forms of welding such as arc welding (which was developed in the early 19th century), explosion welding was developed relatively recently, in the decades after World War II.
