Water covering type explosive welding method of metal compound

Abstract

The invention provides a water covering type explosive welding method of a metal compound. The method comprises the steps of polishing a base plate (1) and horizontally arranging on a clay foundation (5); uniformly arranging a plurality of supports (7) on the base plate; horizontally arranging a compound plate (3) on the base plate through the plurality of supports; adhering an explosive frame (2) to the surrounding of the compound plate through an adhesive bag in the length and width directions; uniformly paving explosive (6), wherein the explosive is paved and controlled to be 2.4 to 4.0g/cm<2> in height H; arranging a water box (8) on the explosive frame and staggering to form a gap for storing detonator (1); slowly pouring water (9) into the water box and keeping the depth less than or equal to H/2; detonating the explosive through the detonator during explosive welding. According to the method, water in the water box can slow down the explosive energy upwards diffusing and can also raise the explosive utilization rate during explosive welding; meanwhile, water can be atomized when the explosive is detonated, and therefore, a large amount of poisonous gas generated by explosive welding can be absorbed by the atomized water, and moreover, lots of clay dust and explosion-caused dust can be collected so as to reduce the pollution to the working environment.

Description

technical field [0001] The invention belongs to the technical field of metal composite materials, and in particular relates to a water-covered metal composite explosive welding method. Background technique [0002] Explosive welding is essentially a metal welding method that combines pressure welding, fusion welding and diffusion welding with explosives as energy sources. When the explosive placed on the doubler plate is detonated by the detonator, the chemical reaction of the explosive explosion will propagate forward at the detonation speed on the doubler plate after a period of acceleration. With the advancement of the detonation wave and the rapid expansion of the explosion product, The chemical energy of the explosive is converted into the high-speed detonation wave and the kinetic energy of the explosion product, and then a part of the kinetic energy is transferred to the doubler plate, thereby pushing the doubler plate to move towards the base plate at high speed, and...

AI Technical Summary

Problems solved by technology

However, in the traditional explosive welding process, there is no constraint on the explosive, so the sparse wave generated during the explosion can quickly reduce the explosive force F and affect the action time t of the explosive force on the double plate, thereby reducing the utilization rate of explosive energy ;

[0006] 2. A large amount of dust is produced at the explosion site

Due to the strong force of the explosion and the relatively dry dust, it is difficult for the dust to fall down quickly, which will have a great impact on the health of the workers on site.
