EXPLOSION BONDED CLAD PLATE

Explosion bonded plate is a new type of composite material, which is made of
two layers of metal plate welded by explosion. This material has high strength,
high toughness and excellent protective performance, and is widely used in the
military, aerospace, automotive and construction fields. It can be welded and
performed at large area. The two layers of metal plates can be the same metal
or different metals. One metal plate can be welded in a "cover" way to another
metal plate. During production process, explosive quantity is much more
important, which explodes in a safety environment. During the explosion welding
process, the explosion produces high temperature and high pressure to make the
two metal plates to quickly squeeze into each other and form chemical bonding.
At the same time, due to the inertia and recoil force of the explosion
byproduct, a very uniform interface is formed between the two metal plates, and
there are a large number of microstructural defects on the interface.

These microstructural defects include dislocations, twinning, grain boundaries
and so on. They have important effects on both the mechanical properties and
the protective properties of the materials. For example, the dislocation can
increase the plastic deformation ability of the material, the twinning can
improve the toughness and fracture toughness of the material, and the grain
boundaries can effectively block the expansion of cracks.

Benefits of Explosion Bonded Clad Plate
a. The Explosion Bonded Clad Plate is the metal clad plate produced by the
explosive bonding method. It owns core advanced benefits as followings:

The Explosion Bonded Clad Plate does not change the chemical compositions and
physical states of the original materials.

The Explosion Bonded Clad Plate's combined surface is in a wave structure
condition, its binding strength and tensile strength are stronger. Other
technology can’t reach its effect.

The Explosion Bonded Clad Plate is hard to separate or crack during the hot
treatment, leveling, cutting, coiling, flow forming etc.

The Explosion Bonded Clad Plate thickness range is wider: The surface square is
6.45cm²~78.87m², its thickness is usually 1~30mm, and there are no specail
limits for the base metal. Its total thickness for the stainless steel clad
plate is more than one hundred mm, like clad tube sheets. There is no quantity
limit.

The base metal is a carbon steel, cladding materials are other precious metals
which can be two layers or more.

The explosive welding can make incompatible metals welded.

so the explosion clad plate is advanced on its performances, especially anti-
corrosion and wear resistance.

b. Explosion bonding is also called explosion welding that refers to a welding
method which uses the shock wave to drive the metal movement, collide on the
surface of the two metals, form a jet, remove the surface mask, and form a
metallurgical connection under the action of the shock wave under the high
pressure. The high energy rate processing technology released by the gunpowder
explosion is used to realize the solid phase welding method.

Special Properties of Explosion Bonded Clad Plate
In addition, explosion bonded clad plate owns special properties. For example,
It can absorb shock wave and explosive energy to some extent and convert it
into heat or mechanical energy, which makes it widely used in areas such as
protective equipment and vehicles. The combination of aluminum and steel, the
combination of titanium and steel are difficult to weld by conventional
methods, even if special measures are taken, its welding quality is difficult
to guarantee. But explosive bonding method is nicer for their combination.

The explosion welding method was proposed in the 1940s. More than a decade
later, the explosion welding technology has been introduced into the industrial
engineering.
