Because of its excellent corrosion resistance, nickel based alloys are widely used in chemical equipment, nuclear industry, marine engineering, aerospace industry, salt making equipment, environmental protection engineering and so on. However, nickel based alloys have high nickel content, so the cost of using all metal nickel alloys is high. The appearance of nickel base alloy composite plate not only reduces the thickness of nickel base alloy, but also ensures the integrity and safety of structure with carbon steel base. It is a great invention and new application direction of materials since the 1960s and 1970s.

Explosive welding is a kind of welding method which uses the energy produced by explosive explosion as energy to form solid phase bonding of the metal to be welded. It is not only an important connection method of metal parts (components), but also a basic metal material composite technology. The metal composite materials made by explosive welding have comprehensive properties and high performance price ratio which are incomparable to single metal, especially can save precious and rare metals. Therefore, explosive welding has an irreplaceable position in the field of material synthesis and processing.
