Description

Ultrasonic welding stress relief is to use high-power ultrasonic waves to drive impact tools to impact the surface of metal objects at a frequency of more than 20,000 times per second. Due to the high frequency, high efficiency and high energy of the ultrasonic waves, the metal surface has a large compressive plasticity. At the same time, the ultrasonic shock wave changes the original stress field and generates a certain value of compressive stress, so that the ultrasonic shock part can be strengthened.

Advantage:

Stable performance: can work continuously for a long time.

Ideal use effect: more than 30% residual stress can be eliminated.

Easy to use: Ergonomic design, light weight, portable and easy to use.

It is not limited by the shape, structure, material, weight, plate thickness and site of the workpiece.

It is used to eliminate welding residual stress and can completely replace aging methods such as heat treatment.

The professional design of the impact head completely eliminates the problem that traditional aging equipment and equipment in the same industry are cumbersome to operate and cannot be operated on site, reducing the workload of on-site personnel.

The stress relief effect is better for on-site welding of large structural parts, ultra-high and ultra-low weld processing, and welding repair welds.

Economical, practical, environmental protection, energy saving, safe and pollution-free.

Effect:

1. Turn the residual tensile stress in the surface layer of the metal weld into compressive stress, thereby greatly improving the fatigue life of the metal structure.

2. Change the metal grain structure in the surface layer 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.

Application field: Industries that have stricter requirements on the stability and strength of the weld. Such as: metal welding processing in bridge, electric power, shipbuilding, pressure vessel, steel structure and other industries.

It is suitable for post-weld treatment of welded structures of various materials, to achieve the purpose of extending the fatigue life of welded structures and improving their fatigue strength, and can eliminate the stress and residual stress in the welding process, especially for common joints, load-bearing joints and dissimilar material welded joints Post-weld treatment of structures.
