Description
Technical field
The present invention relates to the welding methods in shipbuilding technical field more particularly to a kind of hull small space.
Background technique
Since in surface navigation, ambient humidity is big, metal material is easy to be corroded ship, therefore the welding of hull everywhere is logical
The gap that junction is filled up using two-sided welding is required, often to meet the anticorrosion requirement of commissure.Hull interior needs to weld
The a large amount of plate for playing structural support and connection function is connect, in some small spaces of hull, because space limits, in order to realize
Two-sided welding, needs additionally to open up odd-job hole on nigh hull, and construction personnel could be narrow by odd-job hole
Small space interior carries out welding, when the welding is completed, then blocks odd-job hole.
There are more stringent Structural strength calls in certain important support structures of hull, opening up odd-job hole will lead to
Intensity is not up to standard, therefore cannot achieve conventional two-sided welding in the small space near this kind of important support structure, it is difficult to
Meet the anticorrosion requirement of weld.Secondly, there are also some small spaces nearby to have no the position that can open up odd-job hole,
Also it cannot achieve two-sided welding.In addition, because open up odd-job hole can to Ship Structure caused by certain destruction, it is also necessary to shipowner
Core is examined with ship, links up higher cost.
Summary of the invention
The purpose of the present invention is to provide the welding methods in a kind of hull small space, are not needing to open up odd-job
Welding is carried out in the case where hole and meets anticorrosion requirement.
To achieve this purpose, the present invention adopts the following technical scheme:

Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
In the present invention unless specifically defined or limited otherwise, fisrt feature second feature "upper" or "lower"
It may include that the first and second features directly contact, also may include that the first and second features are not direct contacts but pass through it
Between other characterisation contact.Moreover, fisrt feature the "upper" of second feature include fisrt feature second feature just
Top and oblique upper, or first feature horizontal height is merely representative of higher than second feature.Fisrt feature is in the "lower" of second feature
It is directly below and diagonally below the second feature including fisrt feature, or is merely representative of first feature horizontal height less than second feature.
As shown in Figure 1 to Figure 2, the welding method in the hull small space of the present embodiment includes the following steps:
Firstly, making sealing plate 1 and backing plate 2 according to the cross sectional shape of the small space of hull 100, then sealing plate 1 is fixed on
On backing plate 2, then the welding position that sealing plate 1 and backing plate 2 navigate in small space is welded and fixed, forms weld seam 200, closing
Small space obtains confined space 300.
The welding manner that welding method in the hull small space of the present embodiment is combined using sealing plate 1 and backing plate 2 is direct
The small space of hull 100 is closed, is to reach the anticorrosion requirement of welding by single-sided welding, avoids in hull
The destruction caused by structure of odd-job hole is opened up on 100, greatly reduces difficulty of construction, because without hull caused by aperture
100 structure is destroyed, and without the audit that shipowner and ship examine, improves construction efficiency.Since confined space 300 is closed sky
Between, it is isolated from the outside world, therefore be not readily susceptible to corrode, without carrying out paint work in confined space 300, improves construction effect
Rate.
The size of sealing plate 1 and backing plate 2 is obtained by Software Create or after field survey, in the present embodiment, sealing plate 1 and pad
The size of plate 2 after field survey by obtaining, because the error that practice of construction generates is inevitable, therefore actual size and theoretical values
Deviation can be generated, live field survey keeps the size of sealing plate 1 and backing plate 2 more accurate, therefore is easier to assemble, the quality of welding
Also higher.
Specifically, sealing plate 1 and backing plate 2 make with the following method:
Firstly, the lines being closed of crossing in small space, determine 200 position of weld seam of welding, to lines
It measures, obtain the outline data of backing plate 2 and makes backing plate 2, after then carrying out scaled down to the outline data of backing plate 2
The outline data of sealing plate 1 is obtained, sealing plate 1 is produced.When lines do not include curve, can directly be surveyed with tools such as simple tape measures
The length for measuring each side is measured when lines include curve using tools such as laser radars.
Sealing plate 1 is used as supporting element, needs to weld with hull 100, needs that there are between certain between sealing plate 1 and hull 100
Gap is that weld seam 200 provides space, and by adding backing plate 2, weld seam 200 can be accommodated by making to be formed between sealing plate 1, backing plate 2 and hull 100
Groove structure, weld seam 200 by fill this groove structure, be completely filled up the gap between sealing plate 1 and hull 100, because
This obtains good leakproofness.
Backing plate 2 is that weld seam 200 provides the support of side, so that molten bath when welding is kept specific shape, preferably blocks
Gap between sealing plate 1 and hull 100, therefore backing plate 2 needs and hull 100 abuts, the size of the size of backing plate 2 than sealing plate 1
It is bigger.In some embodiments, the edge of backing plate 2 protrudes from the edge of sealing plate 1 everywhere, make the edge of sealing plate 1 everywhere with
Hull 100 is spaced, so that weld seam 200 be made to be closed, improves the airtightness of welding.
Further, sealing plate 1 is fixed with 2 spot welding of backing plate, since backing plate 2 is not involved among structural strength, it is only necessary to slightly
It is fixed, is connected to sealing plate 1 on backing plate 2.
In some embodiments, the middle part of backing plate 2 offers several apertures, is equally since backing plate 2 itself does not play
Supporting role, therefore several apertures can be opened up on backing plate 2 for mitigating the weight of backing plate 2, it is easier to assembled in situ.
Preferably, the thickness of backing plate 2 is less than the thickness of sealing plate 1, to mitigate the weight of backing plate 2, while also saving backing plate 2
Manufacturing cost, reduce the manufacture difficulty of backing plate 2.
Specifically, backing plate 2 is made of sheet metal, the thickness of backing plate 2 is between 0.2 millimeter to 3 millimeters.In individual cases
Under, the edge of backing plate 2 may include several curved segments, and therefore, relatively thin backing plate 2 is easy to happen shape under the effect of external force
Become, the size of backing plate 2 can be done slightly larger, the surplus of some assembly is provided, until practical set, because its be easier to it is curved
Song, can live simple tool flexion, modify backing plate 2, keep the fit-up gap between backing plate 2 and hull 100 smaller, into one
Step improves the leakproofness of welding.
Preferably, it is provided with vapour phase inhibitor in confined space 300, vapour phase inhibitor is adsorbed on metal watch after volatilizing
Face forms fine and close protective film layer to play the role of antirust.Specifically, being welded with hook in confined space 300, gas phase is slow
Erosion agent is suspended on hook, so that it is volatilized more abundant, anticorrosion ability is more preferable.
