Explosion welding process for layered metals

First, the explosion before the preparation
(1) compound plate: explosion composite plate compound plate conventional materials are: titanium-based alloy, nickel-based alloy, Hastelloy, stainless steel, two-way stainless steel, copper, aluminum and other materials. Specifications customized by the customer's requirements, most of the compound plate needs welding. Welding methods are: argon arc welding, plasma welding, arc welding. The industry usually use argon arc welding, welding process considerations are: the purity of argon gas required in 99.99 percent, the welding current according to the thickness of the plate as well as the material of the plate. The positive and negative sides of the weld in the welding process need to be protected by a protective cover to prevent oxidation of the weld, to ensure the quality of welding.
(2) Substrate: the preparation of the substrate will first remove the oxidized skin with an abrasive wheel, and then polished with a thousand pages wheel, to make the surface smooth and flawless.

(3) with the plate: will be welded to a good compound plate calibration and polishing with the prescribed substrate. Composite plate explosion requirements, compound plate must be larger than the substrate.
Second, the explosion site
Composite plate explosion site requirements in the field, ten kilometers away from residential housing, the site requires soft soil, there shall be no stone, to prevent damage to the surface of the plate during the explosion.
Third, explosion welding
According to the specifications of the composite plate material to repair the size of the ground (known in the industry as the turret) after the turret is repaired, the prepared substrate paved, clean up the dirt on the composite surface. According to the process to pave the gap, and then the compound plate placed on top of the gap. Lay the explosives, insert the detonator, ready to detonate.
Fourth, after the explosion
Explosion forming composite plate cleaned up, ultrasonic flaw detection, flaw detection of unqualified parts of the mark, and then repair. After the heat treatment. Heat treatment temperature according to the performance of the material.
Composite plate heat treatment after calibration, calibration after the second flaw detection, to prevent cracking in the calibration process. Finally, the qualified composite plate will be cut and polished. And then finished product inspection, qualified packaging and delivery.
