Abstract
A kind of steel construction technique crosses the method for blocking of welding hole, using following steps：One：Several welding holes excessively are opened up on the steel structure member for needing to assemble；Two：45 degree of bevel is opened up in the edge for crossing welding hole；Three：After the completion of the welding of Standard weld seam, blocked to crossing welding hole；During closure, closure welding is carried out from the edge away from bevel to opening up bevel edge and cross welding hole welding sequence.The present invention solves the problems, such as a large amount of weld defects directly caused by sealing weldering, can not only effectively increase the soldering angle of welding hole closure, improves the accessibility of welding point；Moreover, beneficial to welding interior stress is reduced, the quality of steel construction product is improved, avoids the hidden danger of steel construction safety in production.
Description
Technical field
The present invention relates to steel construction, more particularly to a kind of method for blocking that welding hole is crossed for steel construction technique.Belong to ocean
Oil, ship and building engineering field.
Background technology
Under normal circumstances, built for ocean engineering, ship and other steel constructions when assembling, in order to avoid cross-seam or
Person realizes two-sided welding, it is necessary at primary and secondary strong structure cross-seam and difficulty or ease realize that the position of two-sided welding opens up substantial amounts of work
Skill crosses welding hole.Blocked after the completion of component assembling, it is necessary to cross welding hole to substantial amounts of technique.
Existing method for blocking is directly to cram welding hole using sealing weldering.But it is smaller due to crossing welding hole size, because
This, easily produces the weld defects such as incomplete fusion, lack of penetration and surface crack, and certain hidden danger is brought to safety in production.Due to sea
It is high-risk, excessive risk engineering project that foreign engineering, ship and other large-scale steel structures, which are built, it is necessary to ensure that Earthquake response it is each
Connecting link is safe and reliable.Therefore, it is badly in need of the method for blocking that a kind of safe and efficient technique crosses welding hole.
The content of the invention
It is a primary object of the present invention to overcome disadvantages mentioned above existing for prior art, and provide a kind of steel construction technique mistake
The method for blocking of welding hole, it is by opening up 45 degree of grooves crossing welding hole prefabrication phase, using the welding procedure of deposited metal, from remote
Edge from groove is filled closure to the edge for opening up groove, solves a large amount of weld defects directly caused by sealing weldering
The problem of, it can not only effectively increase the soldering angle that welding hole blocks, and improve the accessibility of welding point；It is moreover, sharp
In reducing welding interior stress, the quality of steel construction product is improved, avoids the hidden danger of steel construction safety in production.
The purpose of the present invention is realized by following technical scheme：
A kind of steel construction technique crosses the method for blocking of welding hole, it is characterised in that：Using following steps：
The first step：(1) preparation：When steel construction is built and assembled, two-sided welding or the back of the body are carried out to Standard weld seam
Portion's back chipping welding；(2) when welding, it is necessary to several welding holes excessively are opened up on the steel structure member for needing to assemble；
Second step：Open up steel structure member when crossing welding hole, it is necessary to open up 45 degree unilateral in the edge for crossing welding hole
Groove；
3rd step：After the completion of the welding of Standard weld seam, blocked to crossing welding hole；During closure, from away from unilateral slope
Mouthful edge carry out closure welding to opening up bevel edge and cross welding hole welding sequence.
The angle Selection scope of the bevel exists：Between 30 degree to 70 degree.
The welding hole of crossing is the hole that radius 15 arrives 30mm, and the hole heart is located at the root of Standard weld seam；Large-size crosses weldering
The back side in hole is provided with ceramic substrate.
The welding hole welding sequence of crossing will be followed from remote bevelled edge to the direction of bevelled edge.
Beneficial effects of the present invention：The present invention is because using above-mentioned technical proposal, it in welding hole prefabrication phase excessively by opening
If 45 degree of grooves, using the welding procedure of deposited metal, envelope is filled to the edge for opening up groove from the edge away from groove
It is stifled, solve the problems, such as a large amount of weld defects directly caused by sealing weldering, can not only effectively increase welding hole closure
Soldering angle, improve the accessibility of welding point；Moreover, beneficial to welding interior stress is reduced, the matter of steel construction product is improved
Amount, avoid the hidden danger of steel construction safety in production.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is welding sequence schematic diagram of the present invention.
Major Symbol explanation in figure：
1. welding hole welding sequence, 5. ceramic substrates are crossed in Standard weld seam, 2. welding hole, 3. bevels, 4. excessively.
Embodiment
Such as Fig. 1, shown in Fig. 2, the present invention uses following steps：
The first step：(1) preparation：When steel construction is built and assembled, it is necessary to be carried out to substantial amounts of Standard weld seam 1 double
Face is welded or the welding of back back chipping；(2) when welding, it is necessary to several welding holes 2 excessively are opened up on the steel structure member for needing to assemble；
Second step：When opening up the welding hole 2 excessively of steel structure member, it is necessary to open up 45 degree of list in the edge for crossing welding hole 2
Side slope mouth 3；
3rd step：After the completion of the welding of Standard weld seam 1, carried out using the welding procedure of deposited metal to crossing welding hole 2
Closure；During closure, closure weldering is carried out from the edge away from bevel 3 to opening up the edge of bevel 3 and cross welding hole welding sequence 4
Connect；Meanwhile ceramic substrate 5 can be increased compared with greater than the welding hole back side for size.
The angle of above-mentioned bevel 3 can be selected according to access for welding, and general range is between 30 degree to 70 degree.
The above-mentioned size for crossing welding hole 2 is generally the hole that radius 15 arrives 30mm, and the hole heart is located at the root of Standard weld seam 1；
It can increase ceramic substrate 5 compared with greater than the welding hole back side for size.
Above-mentioned welding hole welding sequence 4 of crossing will be followed from remote bevelled edge to the direction of bevelled edge.
In use, first have to when mounting structure is prefabricated, just open up well welding hole 2 and cross the bevel 3 of welding hole, so
Afterwards, then assembling welding is carried out.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, it is all
It is any simple modification, equivalent change and modification made according to the technical spirit of the present invention to above example, still falls within
In the range of technical solution of the present invention.
