Post Weld Treatment Of Ultrasonic Aging Stress Relief Equipment With Impact Gun
New Technology for Post Weld Treatment of Ultrasonic Aging Stress Relief Equipment with Impact Gun
Description:
Ultrasonic aging stress relief equipment impact gun is a new post weld treatment technology developed domestically and internationally in recent years. It can completely eliminate welding defects such as incomplete fusion, undercutting, and micro pores at the weld toe, as well as eliminate tensile residual stress, generate compressive residual stress, refine grain size, significantly increase the fatigue life of welding structures, and prevent weld cracking.
The principle of the ultrasonic aging stress relief equipment impact gun is to use an ultrasonic power supply to convert 220V AC power into ultrasonic frequency AC power, and then use an ultrasonic impact gun to convert ultrasonic frequency electrical energy into ultrasonic frequency mechanical vibration, pushing the impact needle to collide with the metal surface at high speed, causing plastic deformation and surface hardening of the metal surface and subsurface, and refining the grain size, thereby achieving the effect of strengthening the metal.

Advantages :
1. It can increase the fatigue strength of welded joints by 30% -120% and extend the fatigue life by 5-100 times.
2. Not limited by the shape, structure, material, weight, steel plate thickness, or site of the workpiece.
3. Used to eliminate residual tensile stress in welding, it can completely replace aging methods such as heat treatment.
4. The professional design of the impact gun completely eliminates the problem of traditional time sensitive equipment and equipment in the same industry being cumbersome to operate and unable to operate on site, reducing the workload of on-site personnel.
5. The stress relief effect of on-site welding treatment, ultra-high and low welding treatment, and welding repair welding of large structural components is better.
6. Economical, practical, environmentally friendly, energy-saving, safe, and pollution-free.
