Description

Welding additive welding ultrasonic impact device and operation method
Technical Field
The invention relates to the technical field of 3D printing, in particular to a welding additive welding ultrasonic impact device and an operation method.
Background
With the development of technology, the additive manufacturing technology is gushed, compared with other additive manufacturing technology, the welding additive is low in cost and high in efficiency, and especially, the additive manufacturing advantages of some large-sized components are more obvious, so that the welding additive manufacturing growth is faster. In addition, the welding technology is widely applied to national defense war industry, national family life, and has wide application in the aspects of ships, vehicles, pressure vessels and the like. However, after all, the welding is carried out by locally heating and melting, then cooling to form a welding seam or a welding layer, which is essentially a local metallurgical process, and various welding defects such as oxidation, air holes, coarse metallographic structure grains, stress, strain, cracks and the like can be inevitably generated, so that the material quality, geometric precision and usability of the product are affected.
In order to improve the welding quality, many methods for reducing or eliminating the welding defect have been explored, wherein impact vibration of the weld joint is one of the effective methods. In recent years, a newer and very promising application of Ultrasonic Impact Treatment (UIT) technology developed by the Soviet shipbuilding industry has attracted attention in terms of improving weld quality.
The ultrasonic impact processing along with welding is performed in real time in the process of generating the welding additive product, so that the effect is better: on one hand, the crystal grains can be refined, the structure is improved, and the defects are reduced; on the other hand, the ultrasonic impact treatment along with welding has higher production efficiency due to concentrated working procedures.
The ultrasonic impact treatment following welding principle is: the ultrasonic frequency mechanical vibration energy is immediately transmitted to the welding seam under a certain pressure, so that a plastic deformation layer with a certain depth is generated on the surface of the welding joint in a certain area taking the transition area of the welding seam and the base metal as the center, thereby effectively improving the appearance shape of the welding toe, enabling the welding toe to smoothly transition, reducing the stress concentration degree of the welding joint, even generating compressive stress on the surface, simultaneously refining grains and compact tissues, improving the tissues of the surface layer of the joint, and further improving the fatigue strength and the fatigue life of the welding joint after ultrasonic impact treatment.
At present, technical researches for improving welding quality and reducing welding defects by ultrasonic impact treatment are started in China, but the number of the technical researches is small.
Such as: "Effect of ultrasonic power on porosity microstructure, mechanical properties of the aluminum alloy joint by ultrasonic assisted laser-MIG hybrid welding" was published in Optics and Laser Technology, university of vinca, jia Liu et al 2019; in 2019 of China, large, special steel science and technology company Xie Yutian and the like, a surface ultrasonic impact device (belonging to post-welding impact) applicable to various appearance structures is designed; the 2015 university of Harbin industry He Wenxiong et al discloses a "technique for reducing or eliminating welding deformation and residual stress with welding ultrasonic impact".
The existing ultrasonic impact treatment along with welding stays in theoretical research, and the ultrasonic impact treatment along with welding is not applied to welding additive manufacturing at present due to few technical schemes and specific structures, and further development and improvement are needed due to the fact that the corresponding technical scheme is not available:
1 does not take into account ultrasonic impact pressure adjustment. However, the actual thickness of the welding layer is changed within a certain range, so that the ultrasonic vibrator is changed when being loaded. So that the ultrasonic vibrator is easily deviated from resonance.
2 the existing ultrasonic impact mode along with welding is as follows: the welding gun is welded above the weldment, and the ultrasonic impact head is impacted behind the weldment, so that the welding gun is only suitable for single-layer welding seams. Therefore, it cannot be applied to welding additive manufacturing.
3, the interval adjustment of the welding point position and the impact point position along with welding is not considered: the related research in the industry proves that the effect is best when the impact point is located in the welding high-temperature plastic region, obviously, the welding process is different, the welding pieces are different, and the optimal distance between the welding high-temperature plastic region and the welding gun is different, but the prior art does not consider the adjustment of the interval between the welding point and the impact point. That is, the adjustment of the impact time along with welding is not considered, and the impact point along with welding is difficult to ensure in a high-temperature plastic welding area.
4, the mode of transmitting ultrasonic vibration to a weldment is not clear, but the contact mode is directly related to ultrasonic transmission efficiency, on the other hand, along with ultrasonic impact of welding, an ultrasonic vibrator moves along with a welding gun on a welding layer or a welding seam, and the movement is flexible. The existing welding-following ultrasonic impact head is in planar contact with a welding seam, and although ultrasonic transmission is good, the ultrasonic impact head is difficult to move and an ultrasonic vibrator is easy to swing.
And 5, welding ultrasonic impact along with welding in the welding additive manufacturing process, wherein a welding gun and an ultrasonic vibrator need to synchronously move in a three-dimensional coordinate, and the moving load of the welding additive equipment in the height direction is increased due to the self weight of the ultrasonic vibrator.
In the ultrasonic impact vibration material-increasing manufacturing process along with welding, the welding gun and the ultrasonic vibrator synchronously move and are connected into a component, but a certain distance is needed to be separated (the interval between the welding gun and the vibrator is adjusted to obtain the optimal treatment effect), so that the welding gun and the vibrator are two different points in space. Therefore, in order to synchronize the movement of the welding torch and the ultrasonic vibrator, the movement trace of the welding torch must be clarified.
It can be seen that ultrasonic impact treatment with welding is used for welding additive manufacturing, and there are many dead zones and difficulties in both concept and method, and technological breakthroughs are urgently needed.
The invention provides a welding additive manufacturing along with welding ultrasonic impact device and an operation method, which can implement ultrasonic impact on a welding layer or a welding line in real time, so that the requirements of modern welding additive manufacturing can be met; the device can meet the requirements of different impact pressures and uneven heights of weldments; reducing deflection of the ultrasonic vibrator, and stably moving the ultrasonic vibrator along with a welding gun; the ultrasonic impact position and the welding gun position interval can be adjusted according to requirements, and the adjustment along with the time lag of welding is adapted; the ultrasonic transmission efficiency is high, and the ultrasonic impact treatment effect is good; the system is simple, convenient to use, advanced in technology, novel in method, practical and reliable.
