Background
After the metal materials are welded by adopting various welding methods, the welding seam is easy to generate larger welding residual stress, particularly larger tensile stress is generated on the surface of the welding seam, if the residual stress is eliminated or reduced without adopting a technical means, surface cracks and even cracks are easy to generate when the welding seam is in service, particularly high-strength steel, high-carbon steel or a large thick plate, and cracks or cracks caused by the residual stress on the surface of the welding seam are easy to occur in the seam of the complex welding joint. The traditional method for eliminating the residual stress of welding is to adopt stress relief annealing under the condition that the residual stress of the welding seam can be eliminated to a large extent or completely, but not all welding structures can adopt the stress relief annealing method in actual production.
The ultrasonic welding stress relieving equipment method is a popular post-welding treatment method abroad, and the basic principle of the ultrasonic welding stress relieving equipment is that a high-power ultrasonic wave is utilized to push an impact tool to impact the surface of a metal object at a frequency of more than twenty thousand times per second, and the high-frequency, high-efficiency and focused high-energy of the ultrasonic wave lead the surface layer of the metal to generate larger compression plastic deformation; meanwhile, the original stress field is changed by the ultrasonic welding stress relieving equipment wave, and a certain value of compressive stress is generated; and the impact part is strengthened, and the surface is locally strengthened and the residual stress is eliminated. The method is developed rapidly in the United states in the sixties of the twentieth century, is acknowledged as the most effective method for improving the fatigue performance of a welded structure, and is promoted and applied rapidly in developed countries, and an ultrasonic welding stress relief device is used as a post-welding treatment device, which can improve a plurality of factors affecting the quality of a welding line, such as stress, defects, weld toe geometry, surface strengthening and the like, so that the method has the effect of improving the fatigue performance of the welding joint by half effort, can improve the fatigue strength of the treated welding joint by 50-120 percent, and prolongs the fatigue life by 5-100 times. Due to the adoption of the ultrasonic welding stress relieving equipment, the traditional polishing and deslagging procedures are omitted, the labor time is saved by 20%, the labor intensity is reduced, and the production efficiency is improved. Meanwhile, the method is also widely applied to the following three aspects: (1) Strengthening the surface of the metal part to improve the surface quality and fatigue life of the part; (2) The stress field is regulated, so that welding deformation is reduced, and the dimensional stability of a workpiece is ensured; (3) And carrying out treatment for eliminating welding stress on the local welding repair part of the mechanical part. The method is widely used in foreign mechanical manufacturing engineering, in particular to welding structure engineering with higher requirements on fatigue performance and residual stress elimination.
The ultrasonic impact welding residual stress eliminating equipment generally consists of two parts, namely a power supply and an impact gun, wherein the power supply and the impact gun are connected through a power line, the impact gun is manually held during use, and the welding seam is impacted. At present, a large number of high-strength steel and large-thickness plate welding joints exist in large-scale steel structure production, such as a peripheral anti-collision safety shell in nuclear power engineering, a large-scale pressure vessel and the like, a large number of long and straight or regular welding seams exist in the steel structure, if a traditional ultrasonic impact welding residual stress elimination machine is adopted for eliminating welding stress, the welding seams are a time-consuming and labor-consuming engineering, a large amount of manpower is required for processing, mechanical and automatic welding is easy to realize for a large number of welding seams with straight or large bending radius, and meanwhile, the mechanical and automatic ultrasonic impact welding residual stress elimination can be realized.
