Metal explosive welding is an edge subject between metal physics, explosive physics, and welding technology. It is high-tech with high practical value for metal-to-metal welding and the production of metal composite materials using explosives as an energy source.
Principle of explosive recombination
Explosive welding is also called explosive recombination. It uses the chemical energy of explosives. Under the detonation of explosives, it pushes the clad plate to collide with the base metal at high speed, forming a metal jet near the collision point. The metal jet cleans the oxide film on the surface of the metal to be welded. , And under high temperature and high pressure, a production process that makes two or more metals form a metallurgical bond between atoms.
Explosive composite plate production method
Place the base plate on the basis of tamped blasting, then place the processed composite plate on the base plate, and then lay a layer of explosive on the composite plate, and use the instantaneous high temperature and high pressure generated by the explosive to realize the solid metallurgical bonding between the metal layers. . Although its production process is simple and flexible, it has high technical requirements and is difficult to accurately control. Base material properties (toughness, impact performance, etc.), explosive properties (detonation speed stability, safety, etc.), static parameters (explosive volume per unit area, base composite plate, The choice of spacing, etc., dynamic parameters (collision angle, collision speed, etc.) of the composite plate, as well as weather, have a direct impact on the yield and quality of the composite plate.
Features of the explosive welded composite board:
1. Explosively welded composite plates will not change the chemical composition and physical state of the original materials, and the composite materials to be processed can be individually processed into the best state-required according to actual needs.
2. In an instant, any two or more metals can be welded together, and large-area continuous welding of metal composite materials of various shapes, sizes, and various uses can be achieved.
3. The application performance of the explosive composite board is very good, and it can withstand cold and hot processing without changing the thickness ratio of the composite material.
4. Metal explosive composite materials are usually designed with base metal as pressure-bearing material and composite metal as corrosion-resistant material. This can not only give full play to the performance of different combinations of metal materials but also greatly reduce the consumption of rare and precious metals and reduce the cost of equipment.
Application areas:
The composite materials produced by explosive composite plates have been widely used in petroleum, chemical, shipbuilding, electronics, electric power, metallurgy, machinery, aerospace, and atomic energy industries.
