Background technology
Plated construction is widely used in railway transportation, Marine engineering, aerospace flight vehicle, auto industry, sea The large scale structure manufacturing field such as superstructure of drilling-production platform.Thin plate has that in light weight, processing performance is good(Easy processing, easily Shaping)And the features such as easy to connect, the thin plate dinger thickness degree in this example are less than 5mm solderable metal plate.But thin plate due to its from Body constraint (restraint) degree is small, deform during welding it is larger, deformation include but is not limited to cross-direction shrinkage, longitudinal contraction, rotary deformation, angular deformation and Flexural deformation etc., shown in Fig. 5, wave transformation can be produced due to unstability when serious, and be difficult correction, particularly to one The larger material of a little thermal coefficient of expansions, deformation are particularly acute.Deformation has not only severely impacted structural strength, the system of thin plate in itself Manufacturing accuracy and performance, or even welding operation can be made not continue because of deformation, therefore it is necessary to plate sheet welding Deformed Control Technology, including influence factor caused by welding deformation and control technique are studied, and are put into practice, improved with Instructing manufacture Product quality.
The main method of control thin plate deformation has at present:
The measure of process aspect has:Correctly select welding method and welding material;Prestrain method and rigid fixation.
Rigid fixation is fixed on weldment on sufficiently rigid tire fixture, or interim welding equipment support, with increase The rigidity of component reduces welding deformation, removes again when all weld seams are cooled to room temperature on connection member to be welded and rigidly fixes, at this moment Deformation caused by component will be significantly smaller than welding deformation in a free state.If coordinate arranging for other control welding deformations again Apply, weld industry will be made within product technology tolerance scope.
Reversible deformation rule is to correct thin plate welding deformation by reversely giving more mechanically deforms.Such as when thin plate welds Connect when being deformed into inside arc-shaped deformation, then by giving outside arc-shaped deformation, and deformation extent exceedes inside arc-shaped deformation amount To be corrected.
But the Deformation control of above two method is still not ideal enough, and operate complex.
The content of the invention
The technical problems to be solved by the invention are to provide device and the side of a kind of welding deformation for controlling sheet member docking Method, it can effectively control the welding deformation of sheet member, the correction work of less postwelding.
