Clad or multilayer steel plates are a type of composite material made by combining two or more different metals to achieve optimal mechanical, chemical, and economic properties. These plates typically consist of a base metal, such as carbon steels like ST52 or A516, and a corrosion-resistant cladding layer made of stainless steel, nickel, titanium, and others. The combination of these metals results in a product with high resistance to corrosion, pressure, and heat, while significantly reducing costs compared to fully alloyed plates. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  1. Incoming Material Quality Control<\/strong>
    Base and cladding plates are delivered to the plant and thoroughly inspected to ensure compliance with technical specifications <\/li>
  2. Grind Mating Surfaces<\/strong>
    The contacting surfaces of both plates are ground to remove oxides and surface impurities, ensuring proper bonding.<\/li>
  3. Assembly of Plates and Explosives<\/strong>
    \u2981 The cladding plate is positioned above the base plate with a precise standoff distance.
    \u2981 Special explosives are evenly spread over the top plate.
    \u2981 This setup allows the formation of a metal jet during detonation.
    Explosion Welding
    \u2981 The detonation generates a high-velocity, oblique collision between the plates.
    \u2981 The jet cleans the interface by removing impurities.
    \u2981 A strong metallurgical bond is formed at the interface. <\/li>
  4. Post-Weld Heat Treatment<\/strong>
    Heating is applied to reduce residual stresses and stabilize the microstructure.<\/li>
  5. Flattening<\/strong>
    The bonded plates are leveled and straightened for further processing.<\/li>
  6. Cutting and Finishing<\/strong>
    The plates are cut to final dimensions based on customer specifications.<\/li>
  7. Testing and Inspection<\/strong>
    \u2981 Ultrasonic testing ensures the integrity of the bond.
    \u2981 Dimensional and quality certifications are issued.<\/li>
