Ultrasonic Impact Machine

      Ultrasonic Metal Stress Relieving Machine, uss powerful ultrasonic to drive impact tools, with the frequency of 20KHz, Causing a greater compressive plastic deformation on the surface of the impact metal. At the same time, the ultrasonic wave changes the original stress field, It can effectively eliminate the stress of welded structure by more than 99.8%, Extend the service life of the structural parts more than 10 times.

 Length of Cable: customized, from 3 m to 8 m.

efficacy:

1. The residual tensile stress in the surface layer of the metal weld is changed into compressive stress, thereby greatly increasing the fatigue life of the metal structure.

2. The metal grain structure in the surface layer is changed 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.

5. The stress relief effect is better than the thermal aging;

6, suitable for outdoor work and large structural parts, not limited by shape, size and so on.

6, suitable for a wide range of materials, not subject to material restrictions.

7. Fatigue strength can be increased by 0.5-5 times; fatigue life is increased by 5-10 times; corrosion resistance is increased by four times; and the service life of the workpiece is prolonged.

8. Eliminate micro cracks and slag on the surface of the weld to inhibit cracking.
