UNIQUE TECHNOLOGY

Explosive metal cladding is of great technological importance for the manufacture of advanced metal composites. It enhances conventional methods for clad metal manufacturing such as pad welding or mill rolling.

Explosive cladding is conducted at room temperature, in a ‘cold pressure weld process’. The impact of the explosion produces sufficient energy to cause the colliding metal surfaces to bond in a solid state. It welds metals that cannot be bonded by conventional processes, such as titanium-steel, aluminium-steel and aluminium-copper. It can also be used to weld compatible metals, such as stainless steels and nickel alloys to steel.

BENEFITS

Explosive clad bimetals and multilayer composites of more than two materials demonstrate unique physical properties. Besides the production of new materials, the main reasons for explosive bonding are:

  • high strength
  • corrosion resistance
  • savings resulting from reduced consumption of expensive metals and their alloys
  • special features like high corrosion resistance
  • high temperature resistance
  • excellent electrical conductivity

QUALITY CONTROL

We offer clad metals tested and certified in accordance with customers’ requirements, and in accordance with the following technical standards and codes:
