Firmakes Titanium produces titanium clad steel plate through the technology of explosive welding. First, polish the substrate and the surface of the coating, keep two sheets of metal plate in a certain distance, laid a certain number of explosives on the surface of titanium plate, and detonate at one end of the explosive. The explosion can cause the cladding material to collide with the base material rapidly, the explosion speed can reach thousands of meters per second. Because the steel and titanium plate in the contact point has a very large deformation speed and high pressure, so the fluid behavior shows. At the same time, the oxide film and gas adsorption layer on the two metal surfaces are excluded, and the bonding between the clean metal surfaces is done in an instant. Usually the plate which directly exploded is thick plate, after rolling, processed it into the thin composite plate.
The explosive cladding plates applications:
Application in Civil Field
In the civil field, with the flatness and surface glossiness, copper cladding steel plate is much better than stainless steel plate on mechanical processing performance. With its good heat conductivity, it can substitute for stainless steel since its heat transfer coefficient is 3 times of stainless steel. So it becomes the perfect material for solar water heater, frying-pan, electric rice cooker, etc, such heating and heat transfer devices. Copper-stainless steel clad plate or copper-low-carbon steel clad plate can also make cookware since its good heat conductivity, rigid and nice appearance.
Application in Electronic and Electrical Field
In the fields of electronic and electrical, copper cladding steel plate has been widely used instead of traditional copper and copper alloy to make electronic devices. Armor cable used to be made of copper or copper alloy, however, copper-stainless steel clad metals take the place of copper or copper alloy now, not only ensuring the electric conductivity, and corrosion resistance, but also increasing strength, and reducing thickness.
Application In Machinery Manufacturing
In the field of machinery manufacture, copper cladding steel plate can make heat exchangers, synchronizer cone rings, reducer worm gears, bearing bushes, etc. Copper-steel and aluminum-steel clad metals can make bimetal or multi-metal bearings, bearing bushes, and liner tubes.
Application In Transportation
In the field of transportation, copper cladding steel plate can be used for linear motor's clad induction plate (copper-steel clad induction plate) on light rail locomotive and subway train. This material not only has good electrical conductivity and good in corrosion resistance, but also improves the strength, and reduces the thickness as well as the cost.
Application In Nuclear Power Projects
In the field of nuclear power projects, copper-stainless or copper-nickel alloy, copper-low carbon steel clad metals can make nuclear storage containers. Big copper cladding steel plate can make linear accelerator cavity for high energy physics research.
Application in Marine Engineering Field
In the marine engineering field, copper cladding steel plate and copper-titanium clad plate can make offshore oil platform structure which can meet properties of high strength, seawater corrosion resistance.
Application In Shipbuilding Industry
In the shipbuilding industry, copper cladding steel plate can weld ship parts or warship parts which ensure high strength, seawater corrosion resistance.
Application In Metallurgical
In the metallurgical industry, copper cladding steel plate is used for electroplating, electrolysis electrode, processing electrode for discharge, grounding rod, current conducting arm body, electrode clamp, and an electrode clamping-release device and so on. Copper-steel or aluminum-steel clad metal can be used for bimetal bearing, bearing bush, and liner tube, wear-resistant plate, self-lubricating slide plate, etc.. Copper-steel clad plate can make electrometallurgical furnace and bi-layer water cooling shell & bi-layer crystallizer of melting furnace.
Application In Military Field
In the military field, copper cladding steel plate can make transmitter, not only solves the leakages, joint corrosion such problems, but also simplifies the manufacturing process, and reduces the cost. If making shells with copper-steel-copper clad metals substituting for brass, it will be much cheaper and much better of ballistic performance.

The Explosive welding/explosive cladding is a technology for manufacturing metal-clad materials and a special technique for dissimilar metals welding. It is a combination of mechanics and metal materials science.
The basic principle of explosive cladding:
1, place the cladding plate on the substrate plate, and then put a layer of explosive on the cladding board, and realize the solid metallurgical bonding between the metal layers by using the instantaneous ultra-high pressure and ultra-high speed impact generated when the explosive is exploded.
2, make the cladding plate and the substrate plate high-speed oblique collision through the explosive explosion. The collision peels off and sprays a small amount of metal jet on the contact surface of the material, resulting in a “self-cleaning” effect to expose the solder joint to the non-polluting clean metal. At the same time, the metal body contact surface at the rear of the jet produces solid phase diffusion and fusion welding under the combined action of high pressure, large deformation, high temperature near adiabatic deformation and high temperature compression; the high temperature of the interface after welding It will quickly dissipate heat into the small deformation low temperature substrate, so that the high pressure interface bonding state is quickly quenched and fixed, preventing the metal excessive diffusion reaction and the formation of a large number of brittle phases.
3, The composite interface consists of a direct bond zone, a molten layer and a vortex. This special welding process gives explosive composites two major advantages. First, it can prevent excessive reaction between dissimilar metals, and can weld different kinds of metals that cannot be welded by ordinary fusion welding methods. Second, it is suitable for large-area composite operations and is convenient for manufacturing various cladding materials.
