Problems solved by technology

[0004] At present, the welding method of titanium-steel composite plate (mainly argon tungsten arc welding) needs to use different welding wires to carry out multi-layer and multi-pass welding on the titanium layer, transition layer and steel layer. The welding process is complicated and the cumulative heat input is large. Low welding speed, high welding stress, etc.

Embodiment 1

[0034] refer to figure 1 , 2, which is the first embodiment of the present invention, which provides a method for processing a titanium-steel clad plate 101 based on transition layer control. .

[0035] The above-mentioned full penetration welding method of titanium steel clad plate 101 includes the following steps:

[0036] 1), processing the welding groove 104: at the composite transition line of the welding section of the titanium steel composite plate 101 to be welded, the processing section is a semi-elliptical groove along the length direction of the composite transition line, and the depth of the groove is the semi-elliptical groove 1 / 2 of the short axis a, the long axis b of the semi-ellipse is perpendicular to the joint surface of the titanium cladding 102 and the steel base layer 103 of the titanium-steel clad plate 101 to be welded, and the short axis a of the semi-ellipse is 1-1.6mm , the long axis b=1-2mm; the titanium steel composite plate 101 to be welded aft...

Embodiment 2

[0045] refer to Figures 3 to 6 , is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The clamping and cutting mechanism 200 includes a bottom plate 201 , a first positioning block 202 , a second positioning block 203 and a cutting adjustment plate 204 .

[0046] The bottom plate 201 is a square structure, the first positioning block 202 and the second positioning block 203 are fixedly arranged on both ends of the upper side of the bottom plate 201, specifically at the two end feet on the upper side of the bottom plate 201, and the cutting adjustment plate 204 is located on the first side. A positioning block 202 and the second positioning block 203 are mounted on the same side of the first positioning block 202 and the second positioning block 203 and are slidably connected.

[0047] Since there is a certain space distance between the first positioning block 202 and the second positioning block 203 , the cutting adjustment p...

Abstract

The invention discloses a titanium-steel composite plate processing method based on transition layer control. Use a certain proportion of metal powder to mix evenly to prepare the transition layer; 4) Laser double-sided welding: after assembly and clamping, preheat the titanium-steel composite plate to 100~120 °C; use laser double-sided synchronous welding, and control the line energy during welding. , so that the two sides of the metal are evenly fused; 5) Fixed clamping and cutting: the processed composite board is fixed and installed, and cut according to the required length. The method improves the mechanical properties of the welded joint of the titanium-steel composite plate through the control of the transition layer, simplifies the existing welding technology, and realizes high-quality and efficient welding.

Description

technical field [0001] The invention relates to the technical field of composite plate processing, in particular to a method for processing a titanium-steel composite plate based on transition layer control. Background technique [0002] Because of its great affinity for oxygen, metal titanium can form a dense oxide film on its surface, which can protect titanium from medium corrosion. Therefore, titanium has good stability and corrosion resistance in acidic, alkaline, neutral saline solutions and oxidizing media. Titanium alloys are widely used in petroleum, chemical, metallurgy, seawater desalination, shipbuilding, power and marine engineering. and other industries. However, the cost ratio of titanium alloys is high. Combining titanium with other metals to make metal composite materials can not only exert the excellent properties of titanium, but also reduce costs. Titanium-steel composite materials are such a material. Titanium-steel clad plate is a metal clad plate in ...
