After the metal material is welded by adopting various welding methods, the welding seam is easy to generate larger welding residual stress, especially larger tensile stress on the surface of the welding seam, if the residual stress is eliminated or reduced by adopting a technical means, surface cracks and even fracture are easy to generate when the welding seam is in service, especially high-strength steel, high-carbon steel or a large thick plate, and cracks or fractures caused by the residual stress on the surface of the welding seam are easy to generate on the seam of a complex welding joint. The traditional method for eliminating the welding residual stress is to adopt stress relief annealing under the allowable condition, so that the residual stress of a welding seam can be eliminated to a great extent or completely, but in the actual production, not all welding structures can adopt the stress relief annealing method.
The ultrasonic welding stress relief equipment method is a relatively popular postweld treatment method abroad, and the basic principle of the ultrasonic welding stress relief 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 metal surface layer generates relatively large compression plastic deformation due to the high frequency, high efficiency and large energy under focusing of the ultrasonic wave; meanwhile, the original stress field is changed by ultrasonic welding stress relief equipment waves, and the compressive stress with a certain numerical value is generated; and the method can strengthen the impacted part, strengthen the surface locally and eliminate the residual stress. The method is firstly developed rapidly in the United states in the sixties of the twentieth century in the Ukrainian of the former Soviet Union, is acknowledged as the most effective method for improving the fatigue performance of a welded structure, and is rapidly popularized and applied in developed countries, an ultrasonic welding stress relief device is used as post-welding treatment equipment, and can simultaneously improve a plurality of factors influencing the quality of a welding seam, such as stress, defects, geometrical shape of a welding toe, surface strengthening and the like, so that the method has the effect of improving the fatigue performance of the welding joint with half effort, can improve the fatigue strength of the treated welding joint by 50-120 percent, and prolong the fatigue life by 5-100 times. After the ultrasonic welding stress relief device is adopted for treatment, the traditional grinding 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 treatment is carried out on the surface of the metal part so as to improve the surface quality and the fatigue life of the part; (2) the stress field is adjusted, the welding deformation is reduced, and the dimensional stability of the workpiece is ensured; (3) and (4) 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 requirement on fatigue performance and requirement on residual stress elimination.
Ultrasonic impact eliminates welding residual stress equipment generally comprises two parts, power and impact rifle, both are connected through the power cord, artifical handheld impact rifle during the use, strike the welding seam, because it is bigger to strike the rifle quality, and there is vibrations when strikeing, long-time during operation consumes workman's physical power very much, but it is narrow and small at some spatial position, the welding seam is irregular, the node that the structure is complicated is toward the biggest place of stress concentration that comes, these places only can be suitable for by manual ultrasonic impact rifle, consequently, need light-weighted manual ultrasonic impact rifle, with reduce intensity of labour, the efficiency is improved.
