Abstract
A method of welding deformation being controlled using rectangle steel plate, belongs to cut deal butt welding technical field.Step: several rectangle steel plates (1) are processed in processing factory, semi arch notch (2) is opened up among rectangle steel plate (1) length direction, passes through for butt weld (6)；Rectangle steel plate (1) sliding solid welding is scheduled on to docking weld bond position (5) two sides of first piece of splice plate (3) and second piece of splice plate (4)；After rectangle steel plate (1) fixes, docking weld bond position 5 is welded, is formed butt weld (6)；After butt weld (6) cooling completely, rectangle steel plate (1) is removed, first piece of splice plate (3) and second piece of splice plate (4) butt welding finish completion.The advantage is that postwelding adjustment is greatly reduced using steel plate block rigidity control welding deformation, it is easy to operate, and steel plate block can be reused, and the cost of control welding deformation is greatly reduced, and achieve good economic benefit for company.
Description
Technical field
The invention belongs to cut deal butt welding technical fields, in particular, provide a kind of control using rectangle steel plate and weld
The method for connecing deformation.
Background technique
In cut deal butt welding, control welding deformation often takes the modes such as reversible deformation and postwelding flame straightening, but very
More plate weldings can not take reversible deformation measure due to being influenced by size, weight and field condition, and postwelding flame straightening is taken a lot of work
It is time-consuming, increase construction cost.My unit combines live practical experience by constantly inquiring into, summarize develop it is a kind of completely new
Using the method for rectangle steel plate control welding deformation, and it is applied successfully in Shoudu Iron and Steel Co capital Tang engineering.
Summary of the invention
The purpose of the present invention is to provide a kind of methods using rectangle steel plate control welding deformation, in certain size
Semi arch notch is opened up in the rectangular steel plates of (long * wide * thickness is 300*200*30), notch passes through for weld seam, then by rectangle
The sliding solid welding of steel plate block is scheduled on buttcover plate position while welding, weld seam by semi arch notch, can normal weld, utilize in welding process
The rigidity of steel plate block has resisted the contraction distortion of weld seam, greatly reduces adjustment welding deformation workload, saves the time, reduces
Construction cost.
The present invention is scheduled on splicing steel using rectangle steel plate (long * wide * thickness is 300*200*30) sliding solid welding of machine-shaping
Welding contraction distortion is resisted using the rigidity of rectangle steel plate when welding in plate weld bond position two sides.Specific step is as follows:
The first step processes several rectangle steel plates 1 in processing factory, opens up semicircle among 1 length direction of rectangle steel plate
Arc notch 2 passes through (Fig. 1) for butt weld 6；
The sliding solid welding of rectangle steel plate 1 is scheduled on the docking weld bond of first piece of splice plate 3 and second piece of splice plate 4 by second step
5 two sides of position (Fig. 2, Fig. 3)；
Third step after rectangle steel plate 1 fixes, welds docking weld bond position 5, forms (the figure of butt weld 6
4)；
4th step removes rectangle steel plate 1, first piece of splice plate 3 and second after the cooling completely of butt weld 6
4 butt welding of block splice plate finishes completion (Fig. 5).
It is an advantage of the current invention that greatly reducing postwelding adjustment, behaviour using rectangle steel plate rigidity control welding deformation
Facilitate, and rectangle steel plate can be reused, greatly reduce the cost of control welding deformation, is achieved well for company
Economic benefit.
Detailed description of the invention
Fig. 1 is factory process rectangle steel plate figure.
Fig. 2 is that weld bond position two sides figure is docked in the sliding solid welding of rectangle steel plate surely.
Fig. 3 is the A direction view of Fig. 2.
Fig. 4 is docking weld bond welding figure.
Fig. 5 is that rectangle steel plate is removed after butt weld is cooling, and figure is completed in butt welding.
In figure, rectangle steel plate 1,2, first pieces of semi arch notch, 3, second pieces of splice plate splice plate 4, docking weld bond position
5, butt weld 6.
Specific embodiment
Fig. 1-Fig. 5 is a kind of specific embodiment of the invention.Specific embodiment is as follows:
The first step processes several rectangle steel plates 1 in processing factory, opens up semicircle among 1 length direction of rectangle steel plate
Arc notch 2 passes through for butt weld 6；
The sliding solid welding of rectangle steel plate 1 is scheduled on the docking weld bond of first piece of splice plate 3 and second piece of splice plate 4 by second step
5 two sides of position；
Third step after rectangle steel plate 1 fixes, welds docking weld bond position 5, forms butt weld 6；
4th step removes rectangle steel plate 1, first piece of splice plate 3 and second after the cooling completely of butt weld 6
4 butt welding of block splice plate finishes completion.
