Explosion bonding—also known as explosion cladding or explosion welding—is a specialized industrial process that harnesses the energy of an explosive detonation to create a metallurgical bond between metal components. Like other welding methods, it is based on well-understood and reliable principles, but it stands apart in its ability to join virtually any combination of metals. This includes both those that are naturally compatible and those traditionally considered non-weldable by conventional techniques. The process can also clad one or more layers onto one or both faces of a base metal, with each layer potentially being a different type of metal or alloy.

The technique was first discovered in the late 1950s and, by the end of the 1960s, had been industrialized worldwide. Over the decades, explosion bonding has been continuously refined, with experienced manufacturers codifying the technology and establishing reliable methods for determining bonding parameters. Compared to its early days, today’s capabilities are far more advanced. Modern facilities can produce large plates up to 30 square meters and successfully master complex combinations of metals, including the challenging task of cladding zirconium onto stainless steel.

Explosion bonding has thus evolved from a novel discovery into a mature, globally recognized technology. Its versatility and reliability make it indispensable in industries where joining dissimilar metals is critical to performance, durability, and innovation.
