Ultrasonic welding stress relief is the use of high-power ultrasonic waves to push the impact tool to impact the surface of a metal object at a frequency of more than 20000 times per second. Due to the high frequency, high efficiency, and focused energy of ultrasonic waves, the metal surface undergoes significant compression plastic deformation; At the same time, ultrasonic shock waves alter the original stress field, generating a certain numerical compressive stress; Enhance the ultrasound impact area.

effect:

1. Transforming residual tensile stress within the surface layer of metal welds into compressive stress, thereby significantly improving the fatigue life of metal structures.

2. Changing the metal grain structure within the surface layer to create a plastic deformation layer, thereby significantly improving the strength and hardness of the metal surface layer.

3. Improve the geometric shape of the weld toe and reduce stress concentration.

4. Changing the welding stress field significantly reduces welding deformation and improves the dimensional stability of the workpiece.

Application field: Industries with strict requirements for the stability and strength of welding joints. For example, metal welding treatment in industries such as bridges, electricity, shipbuilding, pressure vessels, and steel structures.
