How Are Clad Plates Manufactured?

Clad plates are typically manufactured using two main processes: explosion bonding and roll bonding.
1. Explosion Bonding: In this process, the two metals to be clad together are positioned in close contact with each other. The assembly is then subjected to a high-energy explosion. The explosion creates a high-pressure shockwave that forces the two metals together at an extremely high velocity. The impact of the explosion bonds the metals together, creating a strong metallurgical bond between them. The explosion pressure deforms and cleans the surfaces, removing any oxide layers or contaminants. This results in a strong and durable bond between the base metal and the cladding material.
2. Roll Bonding: In the roll bonding process, the two metals are cleaned and prepared, ensuring the surfaces are free from contaminants. The surfaces are then brought into intimate contact with each other. The bonded surfaces are passed through a rolling mill, and high pressure is applied to establish a solid bond between the metals. The rolling pressure causes the metals to bond together, creating a clad plate with a strong metallurgical bond. The thicknesses of the base metal and cladding material can be adjusted according to the specific requirements.
Both explosion-bonded clad plate and roll bonded clad plate offer advantages and limitations. Explosion bonding is suitable for larger surface areas and creates strong bonds quickly. Roll bonding is more suitable for thinner cladding layers and allows for greater control over the overall thickness and dimensions of the clad plate.
After the bonding process, the clad plate may undergo further heat treatments or finishing processes to improve the overall properties and dimensions of the plate. These processes may include annealing, leveling, straightening, or machining, depending on the specific application requirements.
It is important to note that clad plate manufacturing requires careful control and expertise to ensure proper bonding, avoiding delamination or other integrity issues. Therefore, manufacturing clad plates is typically carried out by specialized companies with the necessary equipment, experience, and quality control measures to produce high-quality clad plates.
