Jinan Jiugong Electrical & Mechanical Equipment Co., Ltd. is committed to the research, development, and production of JG series ultrasonic impact equipment, vibration aging equipment, and stress detection instruments. Through the continuous exploration of foreign technology and our R&D department, the product's performance and quality have been significantly enhanced. A comprehensive after-sales service system has laid a solid foundation for the company's market share. At the same time, the company has long-standing practical experience and technical advantages in the field of welding stress relief, providing a more robust guarantee for the elimination of internal stresses in metals.
Ultrasonic impact stress-relieving equipment enhances the fatigue strength of metal weld joints and structures, significantly extending their fatigue life; reduces residual tensile stress, creating compressive stress at the impacted areas to improve the workpiece's load-bearing capacity; effectively improves the geometric shape of weld toes, lowering the stress concentration factor at the weld toes with good results; reduces surface micro-cracks and welding defects at the weld toes, inhibiting early crack initiation; strengthens the surface of metal components, improving surface quality and service life. This equipment is efficient, energy-saving, pollution-free, and easy to use, with no limitations on the shape of the workpiece, site, or environment.

Function of ultrasonic impact stress relieving equipment:
1. The stress relief rate of workpiece welding can achieve ideal effects and is currently the ideal equipment for reducing residual welding stress.
2. Time-saving tool holder, made of high-quality steel, with a compact structure and durability. Equipped with a range rod protector to extend the lifespan of the range rod.
3. Stable frequency and constant amplitude control circuitry, with overheat and overload protection capabilities, eliminating the dangers associated with on-site operation.
4. Enhances fatigue strength of weld joints, extending fatigue life.
5. No restrictions on workpiece shape, structure, material, weight, plate thickness, or location.
6. Can be used to reduce welding residual stress, as an alternative to heat treatment and other aging methods.
7. Excellent design reduces the笨重操作 and difficulties of traditional time-sensitive equipment and industry-standard equipment, making it easier to operate on-site and less labor-intensive for personnel.
8. On-site treatment of welds for large-scale structural components, better weld treatments, and stress relief effects of welding repairs are superior.
9. Ultra-wide frequency tracking range, capable of effectively tracking frequency changes caused by external factors.
10. Utilizing superior ultrasonic power conversion devices for robust output.
11. Economical, practical, eco-friendly, energy-saving, and pollution-free.

Ultrasonic Stress Relief Equipment Processing Effect
Extensive experimental data indicates that ultrasonic impact can increase the fatigue strength of steel焊接 joints by 60~180%, and extend their fatigue life by 10~13 years; for non-ferrous metal焊接 joints such as aluminum and titanium, it can boost the fatigue strength by 26~48% and extend the fatigue life by 5~4 years.
Ultrasonic Stress Relief
Ultrasonic impact stress relief technology is an effective method for eliminating welding stress, 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 stress be eliminated, but also the fatigue life and strength of the welding area can be extended, reducing the likelihood of stress corrosion cracking and enhancing the material's toughness and strength.
