Embodiment 1

[0038] An explosive welding method for a bimetal composite plate with special quality requirements, comprising the following steps:

[0039] (1) Blank pretreatment: Through leveling, grinding, polishing and cleaning, the roughness of the blank plate is controlled to be less than 2mm / m, and the rust and oxide on the surface of the blank plate are removed, so that the roughness Ra of the surface of the blank plate to be bonded is less than 0.05mm; polishing and cleaning should be carried out within 15 minutes before welding, and within 5 minutes before welding, it should be cleaned with ordinary medical alcohol again.

[0040] (2) Charge: such as figure 1 As shown, the base plate 1 and the cover plate 2 are placed in parallel through the intermittent support plate 5, and the extension plate 3 is arranged around the cover plate, and the “basin” shaped charge body 4 is installed on the cover plate and the extension plate. The cladding plate and the extension plate are parallel, t...

Embodiment 2

[0065] An explosive welding method for a bimetal composite plate with special quality requirements, comprising the following steps:

[0066] (1) Blank pretreatment: Through leveling, grinding, polishing and cleaning, the roughness of the blank plate is controlled to be less than 2mm / m, and the rust and oxide on the surface of the blank plate are removed, so that the roughness Ra of the surface of the blank plate to be bonded is less than 0.05mm; polishing and cleaning should be carried out within 15 minutes before welding, and within 5 minutes before welding, it should be cleaned with ordinary medical alcohol again.

[0067] (2) Charge: place the base plate and the cladding plate in parallel, set extension plates around the cladding plate, install a “basin”-shaped charge body on the cladding plate and the expansion plate, and the upper and lower surfaces of the charge body are parallel to the cladding plate and the extension plate , the explosives placed directly above the cla...

Abstract

The invention discloses an explosive welding method for bimetal composite boards with special quality requirements. The explosive welding method includes preprocessing blanks; charging powder; and performing explosive welding. In a powder charging procedure, 'basin'-shaped powder charge bodies are arranged on shroud plates and extension plates, upper and lower surfaces of the powder charge bodies are parallel to the shroud plates and the extension plates, and powder charging quantities are acquired by computing according to a formula. The welded rate of the composite boards welded by the explosive welding method reaches 100%, the bonding strength of welded surfaces of the bimetal composite boards meet a bimetal solid-phase metallurgical bonding strength law, bonding interfaces of the bimetal composite boards are finely wavy and are excellent in quality, and accordingly the quality requirements of critical equipment of thermonuclear fusion power generation test reactors on the composite boards are met.

Description

technical field [0001] The invention belongs to the technical field of explosive welding, and in particular relates to an explosive welding method for a bimetallic (316L stainless steel, CuCrZr alloy) composite plate with special quality requirements. Background technique [0002] The thermonuclear fusion power generation test reactor needs a bimetal composite plate with special quality requirements. The composite plate is required to be welded and composited by 316L stainless steel plate and an imported high-purity CuCrZr alloy plate, and the 316L stainless steel plate and CuCrZr alloy plate The thickness ratio is less than 0.5. Traditional welding methods such as electric welding and friction welding have problems such as complex equipment, high cost, low welding strength, and microscopic defects at the bonding interface. The explosive welding process of the composite plate has not been reported at home and abroad. Contents of the invention [0003] Purpose of the inve...
