Description
Technical field
Tightness test method is segmented the present invention relates to one kind, in particular for segmented external and the tightness of welding lines of contact with sea water
Test, belongs to technical field of ships.
Background technology
It is, according to different positions, according to code requirement by hydraulic pressure to defined height, to make hull knot that ship water filling, which is examined,
Structure and weld seam are in certain pressured state, then check the leakage scenarios of weld seam.But this method has following office in use
Limit：（1）Must device supply water and drainage system, the waste of time and manpower is very big, when particularly testing the larger cabin of volume；
（2）Into cabin, the time of water filling and draining is very long；（3）After experiment, ship and building berth are moist, dirty and messy, after off-test, take
Scaffold and ladder belowdecks is wet and slippery, construction and amendment work inconvenience in unseasoned front deck；（4）When outside temperature and
When water temperature difference is larger, the globule can be produced outside cabin, the judgement to defect brings certain difficulty；（5）When finding defect,
Water in experimental cabin must be drained, and be poured water again after defect expressivity.In view of these defects, are widely used air at present
Air seal test is substituted as part, i.e., to air is filled with to defined pressure in cabin, by the suds for examining back of weld
Whether produce bubble judge weld seam whether seepage.But gas pressure test also has following limitation：（1）Part cabin need to separately install close additional
Shrouding, adds workload；（2）When cabin is larger, inflationtime is longer；（3）Inspection personnel's workload is big and efficiency is low, especially
To larger cabin, defect is searched relatively difficult；（4）When temperature is relatively low, antifreezing agent need to be added in suds, operating process is multiple
It is miscellaneous.Ship body welding pre-sealing technology is this several years shipbuilding new technologies just occurred.South Korea in 2005 by examining it has been proposed that welded
The quality of the air tight test weld seam of the internal air flue of seam, the thinking has then carried out practical proof in Samsung Heavy Industries Ltd., and subsequent
The accreditation of related classification society is arrived.The water pressure test and gas pressure test due to this method compared with monoblock type have absolute efficiency advantage,
Other such as Korea Spro enter the large-scale shipyard of heavy industry South Korea and Japanese shipyard is leaped quickly, have carried out correlative study and have actively applied, have obtained
Good effect.
The pre- close property implementation rate of the close property weld seam of advanced shipyard of South Korea and Japan is up to more than 82%, average list at present
Ship construction period shortens more than 20%, shipbuilding cost reduction by more than 6%.
But the technology is in the external contacting surface of body section, close property survey could be carried out because position relationship common people will face upward head
Examination, but foam just drips down not a little while, therefore which detection difficulty is big, and also the spray foam water duration is short,
It is a urgent problem.
The content of the invention
Tightness test method is segmented it is an object of the invention to provide one kind.
The problem to be solved in the present invention is the deficiency of the tightness of welding lines test inconvenience of existing segmented external and contact with sea water.
To realize the purpose of the present invention, the technical solution adopted by the present invention is：
One kind segmentation tightness test method, comprises the following steps：
A is drilled the hole towards internal weld seams, the gas testing device in the peripheral solder in hole on the segmentation wall face being welded；
B installs leak-checking apparatus on welding rod；
C gas testing devices are connected by tracheae with air compressor machine, and the atomization equipped with iodine water is placed with the air inlet of air compressor machine
Device.
D gas testing devices are inflated into weld seam, and leak-checking apparatus is moved on welding rod, are tested either with or without gas leakage；In leak-checking apparatus
Starch water is placed with, once running into gas leakage, because containing iodine in gas, will be changed colour, therefore Detection results are apparent.
The leak-checking apparatus includes balloon, silica gel block, cell body, sealing strip and magnet wheel, and cell body is close to point by magnet wheel
Section wall face, the sealing of segmentation wall face and cell body realizes sealing movement by sealing strip, and cell body is provided with silica gel block, silica gel block
Positioned at the junction of welding rod and cell body, balloon is connected by pipeline with cell body.
The cell body and balloon are built with starch water, for producing chemical reaction.
Advantages of the present invention：Using the fillet welding leakage test method of this technique, can an insertion, should have extensive city
Field prospect.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram for being segmented tightness test method fillet welding leakage test method of the present invention；
Fig. 2 is a kind of enlarged diagram for being segmented tightness test method leak-checking apparatus of the present invention；
In figure：1st, segmentation wall face 2, leak-checking apparatus 3, welding rod 4, gas testing device 5, atomizer 6,
Air compressor machine 21, magnet wheel 22, sealing strip 23, cell body 24, silica gel block 25, balloon.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is further illustrated.
One kind segmentation tightness test method, comprises the following steps：
A is drilled the hole towards internal weld seams, the gas testing device in the peripheral solder in hole on the segmentation wall face 1 being welded
4, for realizing internal supply；
B installs leak-checking apparatus 2 on welding rod 3, for detecting leak source；
C gas testings device 4 is connected by tracheae with air compressor machine 6, and the atomization equipped with iodine water is placed on the air inlet of air compressor machine 6
Just contain iodine vapor in device 5, the air of such air compressor machine suction, for realizing to gas of the weld seam internal strength containing iodine；
D gas testings device 4 is inflated into weld seam, and leak-checking apparatus 2 is moved on welding rod 3, is tested either with or without gas leakage；Leak-checking apparatus
Starch water is placed with 2, once running into gas leakage, because containing iodine in gas, will be changed colour, therefore Detection results are apparent.
The leak-checking apparatus 2 includes balloon 25, silica gel block 24, cell body 23, sealing strip 22, magnet wheel 21, and cell body 23 passes through
Magnet wheel 21 is close to be segmented wall face 1, and the sealing of segmentation wall face 1 and cell body 23 realizes sealing movement, groove by sealing strip 22
Body 23 is provided with silica gel block 24, and silica gel block 24 is located at the junction of welding rod 3 and cell body 23, because welding rod 3 is uneven, so will
Blocked up with silica gel block 24, silica gel block 24 has good elasticity, balloon 25 is connected by pipeline with cell body 23, and balloon 25 has good
Good compressibility, accordingly even when having leaked little water, can also be supplemented up so that water is contacted with welding rod 3 always at once, realized and continued
Monitoring, cell body 23 is transparent material or plastics, is easy to personal observations.
The cell body 23 and balloon 25 are built with starch water, for producing chemical reaction.
After test is good, have after the carry out mending-leakage of leak source, overall outer surface will be polished smooth, surface smoothness will reach 3.2,
Then sampling carries out performance evaluation, takes 6 pieces of samples to carry out load test
Table 4-13 strains record sheet
By Ben Biao it can be seen that every data variation is than more uniform, therefore after weld seam test mending-leakage, reach good
Welding performance, is favorably improved the service life of ship.
