Ultrasonic welding stress relief is to use high-power ultrasonic waves to drive impact tools to impact the surface of metal objects at a frequency of more than 20,000 times per second. Due to the high frequency, high efficiency and high energy of the ultrasonic waves, the metal surface has a large compressive plasticity. At the same time, the ultrasonic shock wave changes the original stress field and generates a certain value of compressive stress, so that the ultrasonic shock part can be strengthened.

Advantage:
Stable performance: can work continuously for a long time.
Ideal use effect: more than 30% residual stress can be eliminated.
Easy to use: Ergonomic design, light weight, portable and easy to use.
Effect:
1. Turn the residual tensile stress in the surface layer of the metal weld into compressive stress, thereby greatly improving the fatigue life of the metal structure.
2. Change the metal grain structure in the surface layer to produce a plastic deformation layer, so that the strength and hardness of the metal surface layer are significantly improved.
3. Improve the geometry of the weld toe and reduce stress concentration.
4. Change the welding stress field, significantly reduce the welding deformation and improve the dimensional stability of the workpiece.
Application field: Industries that have stricter requirements on the stability and strength of the weld. Such as: metal welding processing in bridge, electric power, shipbuilding, pressure vessel, steel structure and other industries.
