TECHNOLOGY

An explosion is commonly associated with destructive action. Explosive cladding technology uses the phenomenon of explosion in a creative way and is of great technological importance in the production of advanced metal composites. It complements conventional methods of producing clad elements, such as overlay welding and roll-bonding. This technology allows joining metals and their alloys, impossible to connect by other industrial methods.

TECHNOLOGY WITH MANY BENEFITS

  1. Explosive cladding allows to manufacture of bimetallic and multilayer metal composites
    in the widest range of metals and its alloys, and in the widest range of layers thicknesses.
  2. Composite materials retain their mechanical, technological, corrosive and current properties; by joining them into the composite they obtain new, expected structural and functional features.
  3. In a specific cases, result of the use of cladded materials is a reduction in the consumption of expensive metals and their alloys.
  4. Explosive cladding technology enables the production of cladded materials in a variety,
    unlimited quantities, from very small to large batches of products, with varying unit sizes.

PROCESS SCHEME

The cladding process performed in industrial conditions requires the construction of the so-called parallel cladding system. The joined materials are arranged parallel to each other, with a certain distance between them. The whole system is usually located on the ground. An appropriate explosive charge is formed on the surface of the clad layer material. As a result of charge detonation, clad material hits the base material with the proper energy, which leads to permanent fusion of the joined metallic surfaces. The obtained joint has a characteristic wavy shape or is flat.
