    Features:

    1. High power and good impact effect

    2. High reliability and long service life

    3. Light weight, portable and easy to operate

    4. Well-designed and widely used

    5. Significant energy saving and cost reduction

    6. The residual tensile stress in the surface layer of the metal weld is changed to compressive stress, thereby greatly improving the fatigue life of the metal structure.

    7. Change the metal grain structure in the surface layer to make it a plastic deformation layer, so that the strength and hardness of the metal surface layer are significantly improved.

    8. Improve the geometry of weld toe and reduce stress concentration.

    9. Change the welding stress field, significantly reduce welding deformation, and improve the dimensional stability of the workpiece.

    What’s is ultrasonic impact treatment

    Ultrasonic impact treatment is a method to efficiently remove the residual tensile stress on the surface of the workpiece or the weld zone, and form a compressive stress on the surface of the workpiece. Can significantly improve the fatigue life and fatigue strength of welded joints. After welding, the toe area is processed to make the transition smooth, thereby reducing the stress concentration caused by the remaining height and eliminating defects on the surface of the toe; at the same time, a large compressive plastic deformation is generated at the toe, which results in residual compressive stress and adjusts the welding Residual stress field, and strengthen and harden the toe area. The above factors effectively improve the fatigue performance of welded joints.Our company’sultrasonic impact equipment control power box adopts modular design and is manufactured by applying advanced production technology based on the use of high-quality materials and components. The control power supply has a frequency phase-locked tracking system, and it is the first to introduce a fully digital-based control power supply. It realizes automatic frequency scanning, detection, tracking, automatic fault detection and protection, preset control of power adjustment and impedance adjustment, man-machine dialogue, software upgrade, etc. The operation is very convenient and reliable.A large amount of experimental data shows that ultrasonic impact can increase the fatigue strength of steel welded joints by 60 ~ 180% and extend the fatigue life by 10 ~ 135 times; increase the fatigue strength of aluminum and titanium non-ferrous metal welded joints by 26 ~ 48% and extend the fatigue life 5 ~ 45 times.Ultrasonic impact gun products have also formed a series of products, which can be widely used in ships, petrochemicals, aviation, railways, wind turbines, steel or composite bridges, heavy lifting machinery and other fields, suitable for post-weld processing of welding structures of various materials To achieve the purpose of extending the fatigue life of the welded structure and improving its fatigue strength, and can eliminate the welding process stress and residual stress to a certain extent, it is especially suitable for post-weld processing of ordinary joints, load-bearing joints and welded joints of dissimilar materials.
