Plywood novel welding structure.
Background technology
Titanium containing chlorine medium to there is extremely strong resistance to corrosion in salt solution, seawater, and due to the height of titanium elements itself
Specific strength, it is in light weight the features such as, be widely used in device fabrication and the part low temperature situation of chemical industry at present.
But titanium is expensive, the titanium price of Unit Weight is about 50 times of common iron, 8 times of stainless steel.Institute
With currently manufactured titanium chemical equipment, a kind of mode is directly manufactured using titanium, and the pressure that this kind equipment can be born is relatively low,
Use occasion is limited；Another kind is to use composite plate form, and titanium plate is combined with carbon steel/low-alloy steel, wherein by basic unit
Carbon steel/low-alloy steel ensures that the intensity of equipment needs, and ensureing the corrosion-resistant needs of equipment by titanium coating, (titanium coating is directly and medium
Contact).In recent years as chemical industry equipment is to high pressure, maximization development, working condition is also more severe, and simple titanium plate material
Material can not meet the production needs of complex device, and titanium-steel composite board is just more and more applied to chemical industry equipment occasions that manufacture.
The coating thickness of titanium-steel composite board is generally 3~8mm, by welding, titanium coating is formed complete corrosion-resistant
Layer, so the quality of coating welding quality directly affects the performance of equipment.Because the chemism of titanium elements is very high, easily
Oxidation, and insoluble in iron (titanium with iron phase is molten crackle occurs), so traditional titanium-steel composite board welding process is often completed
The postwelding of basic unit, basic unit's weld seam side at titanium-steel composition surface add the titanium backing plate with coating uniform thickness, then cover titanium cover plate,
Finally by sealing welding between titanium cover plate and original titanium coating, concrete structure is shown in Figure 1, although this class formation anticorrosive property
It can be guaranteed, but but influenceed for velocity of medium, the medium hydrops situation being especially likely to occur so that the structure
It is not used to some special operation condition requirements.
Utility model content
Technical problem to be solved in the utility model：The flow velocity of medium is have impact on for the welding structure of prior art,
Medium hydrops, the problem of making it be not used to some special operation condition requirements, there is provided a kind of velocity of medium for ensuring device interior is not
It can be influenceed by device structure, and the titanium steel composite board novel welding structure occurred without medium hydrops.
A kind of titanium steel composite board novel welding structure, it is characterised in that including composite plate basic unit, in the composite plate basic unit
On be provided with a titanium coating being adapted with titanium cover plate, a leakage detection apparatus is additionally provided with the composite plate basic unit, described
Titanium backing plate is provided with titanium coating, the titanium coating is welded together with titanium cover plate by lock bottom structure.
In a preferred embodiment of the present utility model, the leakage detection apparatus includes leak hunting aperture, beam section and plug, institute
Stating the position of leak hunting aperture can beat in welded joints as needed, can also occur in weld seam both sides jump discontinuity, also serve as simultaneously
Passage during welding.
In a preferred embodiment of the present utility model, one end of the titanium coating is in a step.
In a preferred embodiment of the present utility model, the titanium coating welds to be formed with titanium cover plate docks lock back welding
Seam, the docking lock back welding seam and the titanium coating, titanium cover plate and other mother metal rounding ofves.
Due to being using above-mentioned technical proposal, the beneficial effects of the utility model：The utility model passes through titanium cover plate and titanium
Lock bottom joint form between coating, it is ensured that the titanium surface amorphism mutation that joint is in contact with medium, weld seam and surrounding
Mother metal rounding off, so as to the reduction hydrops of maximum possible, avoid having an impact the resistance of velocity of medium, in addition, composite plate base
Layer is provided with leak hunting aperture, and as backing gas access apertures during welding, after equipment investment use, whether commissure can be leaked
Carry out detection alarm.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to a kind of titanium steel composite board novel welding structure shown in Fig. 2 to Fig. 5, including composite plate basic unit 100, compound
A titanium coating 300 being adapted with titanium cover plate 200 is provided with plate basic unit 100, is formed between titanium cover plate 200 and titanium coating 300
Docking lock back welding seam 400, its weld metal thickness will meet anticorrosion requirement, and in the present embodiment, one end of titanium coating 300 is in
One step 310, the titanium backing plate 500 of adaptation is welded on step 310, the height of titanium backing plate 500 and the height at its step 310
Concordantly, if it is necessary, before titanium backing plate 500 is adapted to reconditioning titanium steel junction basic unit's weld reinforcement, with ensure titanium backing plate 500 with
The step 310 of titanium coating is flushed, and titanium backing plate 500 and the spot welding of titanium coating 300 of adaptation are fixed.
A leakage detection apparatus 600 is additionally provided with composite plate basic unit 100, titanium backing plate 500 is provided with titanium coating 300,
