Introduction to Ultrasonic Stress Relief Equipment
Our JG series ultrasonic impact equipment control power supply box is designed with a modular approach, manufactured using advanced production techniques based on selected materials and components. The internal control power supply features a frequency lock phase tracking system and is the first to introduce a fully digital control power supply. It achieves automatic frequency scanning, detection, tracking, fault detection and protection, pre-set control for power and impedance adjustment, human-machine interaction, software upgrades, and more, offering convenient and reliable operation.
Ultrasonic impact stress relief equipment, as a post-welding treatment device, simultaneously improves multiple factors affecting weld quality, such as stress, defects, weld toe geometry, and surface hardening. Therefore, it significantly enhances the fatigue performance of weld joints, increasing fatigue strength and extending fatigue life. By utilizing ultrasonic stress relief technology, the traditional processes of grinding and slag removal are eliminated, saving labor time, reducing labor intensity, and improving production efficiency.

Ultrasonic Stress Relief
Ultrasonic impact stress relief technology is an effective method for eliminating welding stresses, with a stress relief rate exceeding heat treatment and vibration aging treatment, reaching up to 100%. By applying ultrasonic impact treatment to welding seams, not only can residual internal stresses be eliminated, but also the fatigue life and strength of the welded area can be extended, reducing the likelihood of stress corrosion cracking, enhancing resistance to brittle fracture, and strengthening the material.

Ultrasonic Stress Relief Equipment Treatment Effect
Extensive experimental data shows that ultrasonic impact can increase the fatigue strength of steel welding joints by 60~180%, extending the fatigue life by 10~13 years; it can also enhance the fatigue strength of aluminum and titanium alloy welding joints by 26~48%, and extend the fatigue life by 5~4 years.
Simultaneously, ultrasonic impact stress-relieving equipment is widely applied in the following three aspects:
Surface hardening treatment for metal parts to enhance surface quality and fatigue life.
2. Adjust the stress field to minimize welding deformation and ensure the dimensional stability of the workpiece.
3. The treatment to reduce welding stress on the localized welding repair areas of mechanical parts should be performed. This method is now widely used in mechanical manufacturing engineering, particularly in welding structures where high fatigue performance is required and residual stress reduction is necessary.
Ultrasound Shock Equipment Shock Frequency:
Ultrasonic impact equipment drives the impact head with high-power energy to strike the surface of metal objects at a frequency of over 20,000 times per second. The focused high energy induces significant compressive plastic deformation on the metal surface. Simultaneously, ultrasonic impact alters the original stress field, creating beneficial compressive stresses. Under high-energy impact, the surface temperature of the metal rapidly increases and cools down, causing a change in the metal tissue of the affected area. This strengthens the impacted area and eliminates or equalizes stresses.
