Description
Technical field
The present invention relates to welding technology field, and in particular to a kind of elimination welding residual stress and distortion with weldering ultrasound rolling
Pressure method.
Background technology
In all welding structures, in welding process material expanded with heat and contract with cold and elastic-plastic deformation due to,
Under the effect of Thermal Cycle non-uniform heat flux, joint area can produce a certain degree of inhomogeneous deformation, so that connecing
Head produces internal stress and welding deformation.Resulting welding deformation and welding stress can produce larger power to welding structure
Learn influence.Therefore must take appropriate measures effective control and adjustment welding stress and distortion in actual production process.
Current substantial amounts of measure and method are applied in regulation and control welding deformation and welding stress.Mainly include：In welding
Preceding reasonable selection weld seam form, size, reduce weld seam quantity and reasonable Arrangement position while welding as far as possible, in welding process as far as possible
Suitable welding method and specification are selected, using the prestrain method of auxiliary, is rigidly fixed, additional temp control, weldering in welding
The method for being rolled and being hammered in termination process, also has and is corrected after welding terminates by mechanical means and heating means.
But these methods are not to be suitable in all welding structures, and the method and measure having can not be completely eliminated
Residual deformation and residual stress, and it is simultaneously inaccurate, it is less efficient, it is harmful to environment and workers ' health.Described herein
Ultrasonic burnishing stress-removal deformation method, as a kind of new processing method, welding method used and rule can be passed through in welding
Model pre-estimates the size of residual stress and deformation, then includes supersonic frequency by adjusting the running parameter of ultrasonic burnishing equipment
The parameters such as rate, time and amplitude reach accurate elimination residual deformation and stress, and easy to operate, the green nothing in whole process
Pollution, is a kind of excellent method.
The content of the invention
Regarding the issue above, the present invention provides it is a kind of it is efficient eliminate welding residual stress and distortion with
Weld ultrasonic burnishing method.
To realize the purpose of the present invention, the technical scheme is that：
It is a kind of eliminate welding residual stress and distortion with weldering ultrasonic burnishing method, it is characterised in that：Apply in welding process
Ultrasonic burnishing, the weld seam for just completing solidification to welding in welding provides certain ultrasonic energy and pressure is acted on；It is described
Ultrasonic burnishing equipment there is columned probe, weld seam plane is rolled in welding process, pass through adjust ultrasound rolling
The parameter of equipment is pressed to reach accurate elimination stress and deformation.
Further, above-mentioned elimination welding residual stress and distortion with weldering ultrasonic burnishing method, described ultrasound rolling
The process that is rolled of pressure equipment carries out in welding process, rather than weld be fully finished after carry out.
Further, above-mentioned elimination welding residual stress and distortion with weldering ultrasonic burnishing method, described ultrasound rolling
Press the relevant parameters such as pressure and supersonic frequency of the equipment during ultrasonic burnishing can be according to institute's welding material and welding method phase
It should set, residual stress and deformation is adjusted flexibly in realization.
Further, above-mentioned elimination welding residual stress and distortion with weldering ultrasonic burnishing method, described welding side
Method includes the welding methods such as MIG, MAG, TIG, submerged-arc welding, Laser Welding, plasma weldering, electron beam weldering.
Further, above-mentioned elimination welding residual stress and distortion with weldering ultrasonic burnishing method, described welding side
Method is applied to the modes such as overlap welding, butt welding.
The beneficial effects of the invention are as follows：The method of the present invention can be with more accurate elimination residual deformation and stress, and works
Temperature is low, efficiency high, easy to operate, green non-pollution, it is easy to promote the use of.
Brief description of the drawings
Fig. 1 is the inventive method schematic diagram.
In figure, 1, ultrasonic burnishing equipment, 2, welding equipment, 3, welding material, 4, weld seam.
Embodiment
As shown in figure 1, the ultrasonic burnishing equipment 1 used has columned probe, welding material 3 is docked before welding
Or overlap, welding material 3 is placed under ultrasonic burnishing equipment 1.During welding, welded using welding equipment 2,
Welding is completed after one section, and the probe distance of electric arc to be welded and ultrasonic burnishing equipment 1 reaches a timing, and now leading portion weld seam 4 is simultaneously
Not cooling completely, begins to use ultrasonic burnishing equipment 1 to carry out ultrasonic burnishing to face of weld, and regulation ultrasonic burnishing equipment 1 is exported
The ultrasonic wave of certain frequency and amplitude, sets rolling speed, consistent with welding direction to carry out precise ultrasound rolling to weld seam 4, with
Welding is carried out simultaneously, so as to reach the purpose that residual stress and residual deformation are eliminated with weldering.After the completion of to be welded, ultrasonic burnishing
It can complete, reach high efficiency, the requirement of high standard.
Fig. 1 show in surface overlaying, but this method practical application be not limited to overlap welding also include such as butt welding its
His method.
