Abstract
A kind of method that use backing plate controls welding deformation, belongs to middle thick flat plate butt-welding control welding deformation field.Step is：Plate thickness is docked according to actual, Welding experiment is first carried out, the back plate sizes that selection matches with experiment afterwards：The long wide * t of *, long 100~200mm, wide i.e. buttcover plate is wide, in the range of thickness t=4~30mm；Backing plate is placed on to the underface of buttcover plate welding position, makes buttcover plate angle identical with the angle of Welding experiment；Plate welding seams layering welding is docked, interlayer cooling, position while welding is gradually tapered up, and is lifted up buttcover plate；After docking plate weld is finished, as weld seam is cooled down, weld seam is finally retracted to the angle for making buttcover plate smooth.Advantage is that the backing plate makes welding position produce opposing angular, recycles the stress in welding process, make weld contraction, finally offset opposing angular, reach buttcover plate postwelding smooth, postwelding adjustment is reduced, it is easy to operate, greatly reduce control welding deformation cost.
Description
Technical field
The invention belongs to middle thick flat plate butt-welding control welding deformation field, in particular, provide one kind and use backing plate control
The method of welding deformation processed.
Background technology
In cut deal butt welding, postwelding welding deformation often takes the tradition side such as postwelding flame straightening and machinery correction
Formula, it is time-consuming, not only increase construction cost, and certain damage is also resulted in mother metal.I inquires into unit by continuous, with reference to
Live practical experience, and pass through repetition test, a kind of method that brand-new use backing plate controls welding deformation of developing is summarized, both
It is placed on the metal mat processed immediately below buttcover plate position while welding, position while welding is formed a kind of opposing angular, welded
Bi Hou, weld seam cooling meat offsets the advance opposing angular of weld seam, makes buttcover plate smooth, reduces postwelding adjustment amount, simple real
With greatly reducing construction cost, technique is applied successfully in Shoudu Iron and Steel Co Qin plate engineering.
The content of the invention
It is an object of the invention to provide a kind of method that use backing plate controls welding deformation, by docking steel plate weld seam
The mode of backing plate is added immediately below position, is offset in postwelding due to the deformation that weld seam cooling meat is produced, postwelding adjustment work is reduced
Measure.Comprise the following steps that：
The first step, docks plate thickness according to actual, first carries out Welding experiment, the backing plate chi that selection matches with experiment afterwards
It is very little：In the range of wide (buttcover plate is wide) the * t (plate thickness) of long (100~200mm) *, general t=4~30mm (Fig. 1)；
Second step, backing plate is placed on the underface of buttcover plate welding position, makes the angle of buttcover plate angle and Welding experiment
Spend identical (Fig. 2)；
3rd step, docking plate welding seams layering welding, interlayer cooling, due to producing welding stress, position while welding is gradually tapered up,
Buttcover plate is set to be lifted up (Fig. 3)；
4th step, after docking plate weld is finished, as weld seam is cooled down, due to welding stress influence, weld seam is finally retracted to
Make the smooth angle of buttcover plate (Fig. 4).
The backing plate makes welding position produce opposing angular, recycles the stress in welding process, makes weld contraction, finally support
Disappear opposing angular, reaches buttcover plate postwelding smooth, reduces postwelding adjustment, easy to operate, greatly reduces control welding and becomes
This is formed, is that company achieves good economic benefit.
Brief description of the drawings
Fig. 1 is backing plate schematic diagram.
Fig. 2 is that backing plate makes weld seam produce opposing angular schematic diagram.
Fig. 3 is weld contraction schematic diagram in welding process.
Fig. 4 is that postwelding weld contraction finishes the smooth schematic diagram of buttcover plate.
Embodiment
Fig. 1-Fig. 4 is a kind of embodiment of the invention.Embodiment is as follows：
The first step, plate thickness, advanced Welding experiment, the backing plate chi that selection matches with experiment afterwards are docked according to actual
It is very little：In the range of wide (buttcover plate is wide) the * t (plate thickness) of long (100~200mm) *, general t=4~30mm；
Second step, backing plate is placed on the underface of buttcover plate welding position, makes the angle of buttcover plate angle and Welding experiment
Degree is identical；
3rd step, docking plate welding seams layering welding, interlayer cooling, due to producing welding stress, position while welding is gradually tapered up,
It is lifted up buttcover plate；
4th step, after docking plate weld is finished, as weld seam is cooled down, due to welding stress influence, weld seam is finally retracted to
Make the angle that buttcover plate is smooth.
Claims (1)
1. a kind of method that use backing plate controls welding deformation, it is characterised in that
