Abstract
A kind of cross weld seam did not opened the welding method of welding hole, including step：In flange plate butt weld and web right-angled intersection position, in the case where not opening welding hole, flange plate is propped up to certain height；The sturdy ceramic backing in inner side continuity ground, outside single face welding and double face shaping, makes butt weld keep continuous at web；After butt weld Non-Destructive Testing qualification, reverse side reinforcement is removed, completes the weld seam between web residue position and upper lower flange.Above-mentioned welding method, ensure that continuity of the lower flange butt weld at web position, improve the quality of weld seam and integrally-built anti-fatigue performance.
Description
Technical field
The present invention relates to the welding method that a kind of cross weld seam did not opened welding hole.
Background technology
In flange plate butt weld and web right-angled intersection position, usually rely on and opened up welding hole in web correspondence position
Mode is handled.And when being related to the excessive situation of the position Fatigue Stress Amplitude, opening up welding hole can not meet that structure is tired
The requirement of labor stress, influences bridge structure safe.
The content of the invention
Its purpose of the invention, which is that, provides the welding method that a kind of cross weld seam did not opened welding hole, solves in flange plate
During the excessive situation of butt weld and web right-angled intersection position Fatigue Stress Amplitude, opened up welding hole can not meet structural fatigue by
The requirement of power, the problem of influencing bridge structure safe.
Adopt the technical scheme that to achieve the above object, a kind of cross weld seam did not opened the welding method of welding hole, bag
Include step：In flange plate butt weld and web right-angled intersection position, in the case where not opening welding hole, flange plate is propped up one
Fixed height；The sturdy ceramic backing in inner side continuity ground, outside single face welding and double face shaping, makes butt weld company of holding at web
It is continuous；After butt weld Non-Destructive Testing qualification, reverse side reinforcement is removed, completes the weld seam between web residue position and upper lower flange.
Beneficial effect
The present invention has the following advantages compared with prior art.
The continuity of effective guarantee web interconnection position butt weld of the invention, and weld seam can effectively be examined
Survey, it is ensured that welding quality.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is flange plate butt weld of the present invention and web right-angled intersection position structure detail figure；
Fig. 2 is the schematic diagram after the present invention struts upper and lower flange plate；
Fig. 3 is the schematic diagram after the completion of flange plate docking above and below the present invention；
Schematic diagrames of the Fig. 4 between web residue position of the present invention and upper lower flange after the completion of weld seam.
Shown in figure：1st, top flange, 2, lower flange, 3, web, 4, top flange butt weld, 5, lower flange butt weld,
6th, ceramic backing, 7, web residue position and the intermarginal weld seam of upper limb, 8, web residue position and the intermarginal weld seam of bottom wing.
Embodiment
A kind of cross weld seam did not opened the welding method of welding hole, including step：
1) in flange plate butt weld and web right-angled intersection position, in the case where not opening welding hole, flange plate is propped up；
2) the sturdy ceramic backing in inner side continuity ground, outside single face welding and double face shaping, makes butt weld keep continuous at web；
3) after butt weld Non-Destructive Testing qualification, reverse side reinforcement is removed, completes the weldering between web residue position and upper lower flange
Seam.
Embodiment
As shown in Figs 1-4, an embodiment of the present invention provides the welding method that a kind of cross weld seam did not opened welding hole, the welding
Method includes：In flange plate butt weld and web right-angled intersection position, in the case where not opening welding hole, flange plate is propped up
Certain height；The sturdy ceramic backing in inner side continuity ground, outside single face welding and double face shaping, makes butt weld be kept at web
Continuously；After butt weld Non-Destructive Testing qualification, reverse side reinforcement is removed, completes the weldering between web residue position and upper lower flange
Seam.
Certain height is propped up into top flange 1, lower flange 2, the sturdy ceramic backing 6 in inner side continuity ground, outside single welding
Double-faced forming, makes top flange butt weld 4 keep continuous at web 3 with lower flange butt weld 5；Treat top flange butt weld
4, with after 5 Non-Destructive Testing qualification of lower flange butt weld, removing reverse side reinforcement, complete between web residue position and upper lower flange
Weld seam 7 and web residue position and the intermarginal weld seam 8 of bottom wing.
The major control point of the present invention is that the mode for taking machinery or fire to simmer props up upper and lower flange plate end suitably
Highly, it should ensure there are enough stations to remove sturdy ceramic backing, and cannot be excessive, cause not withdrawing after the completion of butt weld
It is excessive with web gap.
