Embodiment 1

[0029] Fried-rolled large-area titanium-steel clad plate manufacturing. The dimensions of the two titanium plates to be spliced ​​are 6×1500×2050mm and 6×1000×2050mm respectively. The two titanium plates are pressed tightly with welding fixtures. The two titanium plates to be spliced ​​do not open grooves and leave no gaps. Before welding, clean up the oil, water, rust, oxide layer and other dirt in the groove area and the surrounding area within 20mm; first use the plasma arc welding welding method for welding, and conduct non-destructive testing after welding, according to JB4730-2005 Class I. Explosive welding, the base material is Q235B, the size is 70×2480×2030mm, the direction of the detonation wave is perpendicular to the direction of the clad titanium weld; non-destructive testing is carried out on the titanium clad weld after explosive welding, and the test results meet JB / T4730-2005Ⅰ Rolling is carried out after rolling, and non-destructive testing is carried out on ...

Embodiment 2

[0031] Explosion-rolled large-area titanium-steel clad sheet fabrication. The sizes of the two titanium plates to be spliced ​​are 8×1020×1480mm and 8×1020×1480mm respectively. The fixture is pressed tightly, and there is no gap between the two titanium plates to be spliced. Before welding, clean up the oil, water, rust oxide layer and other dirt in the groove area and the surrounding 20mm; first use the plasma arc welding method to weld Bottom welding, and then automatic tungsten argon arc welding welding method for cover welding, non-destructive testing after welding, according to JB4730-2005 Class I, explosion welding is carried out after the base material is Q235B, the size is 60×2020×1460mm, explosion welding The direction of the bombardment wave is parallel to the direction of the clad titanium weld; after the explosive welding, the titanium clad weld is subjected to non-destructive testing, and the test results meet the requirements of JB / T4730-2005 Class I and then rol...

Abstract

The invention introduces a method for producing an exploded / rolled big area titanium steel composite plate. The method including includes the steps of titanium plate splicing, nondestructive testing after welding, explosive welding, nondestructive testing after explosive welding, rolling, nondestructive testing after rolling, and tissue and performance detecting, wherein, when the titanium plate is not more than 7 mm in thickness, the titanium plate is welded by adopting plasma arc welding, thereby finishing the step for titanium plate splicing; when the titanium plate is more than 7 mm in thickness, performing backing weld by using plasma arc welding and then welding the cover surface by employing automatic argon tungsten-arc welding, thereby finishing the step for titanium plate splicing. The method capable of meeting the demands of users for the titanium steel composite plates with different sizes, is unlimited to supply sizes of titanium materials in the current market, less in welding workload, low in production cost and beautiful in welding seam formation; the joints with good toughness can bear the action of great impact of a detonation wave during the explosive welding process and repeated rolling during the rolling process; the heat affected zone of welding is small; and the welding seam is good in quality. By using the process, the problem of the composite layer titanium for the exploded / rolled big area titanium steel composite plate in which the joints are split after the composite plate is exploded and rolled, is solved successfully.

Description

technical field [0001] The invention relates to a manufacturing technology of explosion-rolling large-area composite material, in particular to a preparation method of explosion-rolling large-area titanium-steel composite plate. Background technique [0002] The titanium-steel clad plate produced by the explosion-rolling method is limited by the supply size of the titanium plate in the current market. [0003] In order to meet the different size requirements of users for titanium-steel composite panels, there are two solutions as follows: [0004] One is to splice the explosion-rolled titanium-steel clad plates. This method greatly increases the welding amount of the subsequent titanium-steel clad plate. Not only the clad titanium needs to be welded, but also the base steel needs to be welded. The solubility of iron in titanium is very low, generally only 0.1% (mass fraction), exceeding this limit, Will generate TiFe, TiFe 2 Intermetallic compounds that severely embrittle...
