Its working principle is to produce compressive plastic deformation on the metal surface through high-frequency impact, thereby forming beneficial compressive stress on the surface of the workpiece, changing the original stress field, and enhancing the fatigue strength and life of the welded joint.Ultrasonic stress relief equipment uses high-power energy to drive the impact head to impact the surface of metal objects at a frequency of about 20,000 times per second. High frequency, high efficiency and high energy under focus cause large compressive plastic deformation on the metal surface, while changing the original stress field and generating beneficial compressive stress. Under high-energy impact, the temperature of the metal surface rises rapidly and cools rapidly, causing the surface metal structure of the action area to change and the impact part to be strengthened. ApplicationsUltrasonic stress relief equipment is widely used in various materials, components and welding units, including railways, marine engineering, automobiles, armored vehicles, heavy engineering machinery, mechanical parts, aircraft, bridges, oil pipelines, chemical machinery and equipment, etc.Its specific application effects include:1. Eliminate welding residual tensile stress and convert it into ideal compressive stress, and the residual stress can be eliminated by 80-100%.2. Improve the fatigue strength and life of the welded joint, and extend the fatigue life by 5-100 times.3. Improve the corrosion resistance of metals in corrosive environments by about 400%.4. Improve the geometry of the weld toe, reduce stress concentration, and inhibit crack initiation.5. Suitable for local welding stress elimination of mechanical parts and improving welding quality during welding repair and welding.6. Reduce structural stress and weld cracks caused by temperature changes in different materials after welding.Detailed Photos
