Abstract
The present invention relates to a kind of method for being secured across clearance hole steel sleeve, including increasing clearance hole bore size standard, arranges iron wedge backer and iron wedge step.The present invention preferably ensures that steel sleeve being capable of fixation, it is ensured that welding quality, while when ensureing soldering and sealing clearance hole, welded gaps without departing from《CSQS》Specified in fillet weld seam maximum standard.This method process is simple, efficient and convenient, it can be ensured that welding quality.
Description
Technical field
The present invention relates to needing to observe《CSQS》Product, especially have in field of shipbuilding wide
General application, more particularly to a kind of method for being secured across clearance hole steel sleeve.
Background technology
As shipbuilding industry gets into a difficult position, shipowner is more and more stricter to ship quality requirement, in the past a lot of ignored details
Part, is constantly found, and this is accomplished by new technology new method to make up.
During shipbuilding, find in order that steel sleeve can smoothly pass through clearance hole, and effectively can fix
Steel sleeve, needs to increase original clearance hole by hand, could fill in iron wedge, to reach the mesh of fixing steel sleeve in clearance hole
's.But the manual clearance hole that increases can cause clearance hole to be highly more than 16mm, according to《CSQS》Correlation will
Ask, clearance hole directly can not carry out soldering and sealing process, and the measure that changes plate herein is needed, this considerably increases consumption and the work of material
When, by analysis, original technological process is primarily present following both sides defect：
1. can fill in clearance hole to ensure iron wedge, need to increase clearance hole by hand, original clearance hole is typically high
Spending for 12mm, minimum 5mm to be cut off being cut every time using manual cutting knife, this results in clearance hole and highly reaches 17mm, beyond
《CSQS》Specified in maximum standard 16mm, need to take and change plate process, waste time and energy.
2. while in order to fixing steel sleeve, needing to fill in iron wedge in the middle of clearance hole and steel sleeve, but due to iron
Wedge thickness minimum is also required to 8mm, and the gap between steel sleeve and clearance hole only has 5mm, so the height of clearance hole must be increased
To 20mm, this just far beyond《CSQS》Specified in 16mm, shipowner once has found such case, just must
Must take and change plate.
If not carrying out changing plate according to specification, problems of welded quality when can cause soldering and sealing clearance hole.
In order to the weak point of former method is solved, a kind of method for being secured across clearance hole steel sleeve has therefore been invented.
Content of the invention
It is an object of the invention to the fixation problem through clearance hole steel sleeve is solved, one kind is provided and is secured across clearance hole
The method of steel sleeve, can be used for the fixing means of vertical electrical automatic welding groove reverse side steel sleeve, it is to avoid construction envelope in the past
Weldering clearance hole exceeds《CSQS》, or construct according to standard, but the problems such as consuming a large amount of manpower and materials.
The present invention provides following technical scheme：
A kind of method for being secured across clearance hole steel sleeve, fixes steel for weld groove reverse side in product building course
Liner, including the fixing means of steel sleeve, the perforate standard of clearance hole.
A kind of method for being secured across clearance hole steel sleeve of the present invention, comprises the steps of：
1. basis《CSQS》In with regard to angle welding assembling requirement open up clearance hole, the height of the clearance hole
Spend less than 16mm, more than steel lining mat thickness；
2. iron wedge backer is fixed on mother metal above clearance hole, and iron wedge backer has certain gradient near the side of clearance hole,
Spacing between the upper surface of iron wedge backer and the bottom of clearance hole is 6 between 10mm；
3. steel sleeve is passed through clearance hole, and puts and put in place, then by the middle of iron drift ping to steel sleeve and iron wedge backer, and
Strike tight.
4., after seam welding to be welded is completed, iron wedge, iron wedge backer and steel sleeve are removed, according to《Shipbuilding of China quality mark
Accurate》Clearance hole is welded in soldering and sealing.
It is welded to connect between described iron wedge backer and clearance hole mother metal.
Described iron wedge backer adopts identical material with clearance hole mother metal, and described iron wedge adopts A level steel.
Compared with prior art, the invention has the beneficial effects as follows：Solve conventional method with《CSQS》
Conflicting problem, while also steel sleeve can be fixed well, improves welding quality.According to《CSQS》In
Relevant angle welding clearance criteria opens up clearance hole, it is ensured that soldering and sealing clearance hole meets matching requirements.
Description of the drawings
Fig. 1 is the schematic diagram of the method that the present invention is secured across clearance hole steel sleeve.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
The schematic diagram that Fig. 1, Fig. 1 are the methods that the present invention is secured across clearance hole steel sleeve is referred to, as illustrated, a kind of
The method of clearance hole steel sleeve is secured across, is comprised the steps：
1. in the flat butt welding of high current, substantial amounts of heat can be discharged, causes common ceramic substrate easily to be burnt,
Weldquality problem is caused, so be accomplished by using steel sleeve, for guaranteeing weld root shaping, it is ensured that welding quality, for guaranteeing
Steel sleeve can pass through clearance hole, the height of clearance hole 1 is increased to above more than 14mm, but must be less than
16mm, to guarantee that soldering and sealing clearance hole meets《CSQS》.
2. iron wedge backer 2 is fixed on mother metal above clearance hole, it is ensured that iron wedge backer 2 has certain oblique near clearance hole 1
Degree, iron wedge backer and clearance hole spacing ensure 6 between 10mm.
3. steel sleeve 3 is passed through clearance hole 1, and put and put in place, then iron wedge 4 is filled in steel sleeve and iron wedge backer
Between, and strike tightly, steel sleeve is fixed and is completed.
4., after seam welding to be welded is completed, iron wedge, iron wedge backer and steel sleeve are removed, according to《Shipbuilding of China quality mark
Accurate》Clearance hole 1 is welded in soldering and sealing.
It should be noted last that, above example is only unrestricted in order to technical scheme to be described, although ginseng
The present invention is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to invention
Technical scheme is modified or equivalent, and without deviating from the spirit and scope of technical solution of the present invention, which all should be covered
In the middle of scope of the presently claimed invention.
