Abstract

The invention discloses a protection method of explosive welding. Two different metal plates are superposed, an explosive layer is paved on a metal compound plate, and explosive explodes to obtain a metal compound plate. A protection material layer covers the explosive surface, and a protection material comprises a porous gauze material. An adsorber is arranged on the porous gauze material, the explosive explosion noise is remarkably attenuated, the explosive energy is fully utilized, thus, the problem that the energy utilization rate of explosive used for explosive welding is low is solved, and meanwhile, the problem of environment pollution during explosive welding construction is solved. By means of the protection material, the explosive use amount can be decreased by 40-60%, and the explosion noise can be decreased by 50-80%.

Description

technical field

[0001] The invention relates to the technical field of metal composite plate manufacturing, in particular to a protection method for explosive welding. Background technique

[0002] Metal composite panels are currently widely used in petroleum, chemical, pharmaceutical, shipbuilding, electric power, metallurgy and other industries. With the continuous development of material science and equipment manufacturing technology, the application fields of metal composite panels are becoming more and more extensive.

[0003] Explosive welding is commonly used for the composite of metal plates, that is, the impact force generated by explosive explosion is used to cause rapid collision between metal plates, realize the interface connection of metal plates, and form two or more layers of metal composite materials of different materials. During explosive welding, explosives are usually applied directly on the surface of the doubler board. After the explosive is detonated,...
