Explosive compounding was first discovered in 1944. During an explosive explosion test, the American L.R. Carl accidentally discovered two thin brass discs with a diameter of 1 inch and a thickness of 0.035 inches, which were welded due to the sudden impact of the explosion. together. In fact, in the Second World War, when people were repairing damaged tanks, they often found that the shrapnel that hit the tank obliquely would be firmly welded to the armor of the tank, but people had no time to study it during the war. In 1947, M.A. Lavrentev, a famous scientist of the Siberian Branch of the Soviet Academy of Sciences, also discovered this phenomenon when he was studying the penetration of shaped energy projectiles. He officially called it "explosive welding" in his paper. In the field of welding, the welding of different materials is very technically difficult, such as the welding of steel and aluminum, and steel and copper. Welding with a large welding depth is also very difficult. If you want to use conventional electric welding, shielded welding, and other welding methods to weld two 40mm thick wide and thick plates into one 80mm thick wide and thick plate, it is estimated that no one will do it. However, explosive compounding perfectly solves the two problems at the same time.
Explosive clad board production process: surface treatment of substrate and double board - matching tailor welding - blasting cladding - preliminary investigation - welding repair - heat treatment - inspection - straightening - re-examination - cutting - polishing and packaging.
Explosive composite plates are favored in many fields because they have more than two material properties, such as nuclear power, hydropower, chemical industry, food processing, etc. The advantages of explosive composite plates:
1. High interface bonding strength: the energy of the explosive explosion makes the doubler board hit the substrate at high speed, generating high temperature and high pressure to realize solid-phase welding at the interface of the two materials. For example, the explosive composite of stainless steel and carbon steel, under ideal conditions, the shear strength of the interface can reach 400Mpa.
2. Realize multiple metal cladding: Since explosive cladding is cold processing, it can produce many kinds of metal clad plates other than stainless steel clad plates, such as titanium, copper, aluminum, and so on.
3. Wide thickness range of clad plate: Explosive cladding can produce stainless steel clad plates with a total thickness of several hundred millimeters, such as some large bases and tube plates.
