Description
The 20kHz Ultrasonic Impact Treatment Gun is an advanced surface modification and stress relief system designed for improving the mechanical performance, fatigue resistance, and structural integrity of metal components. It uses high-frequency ultrasonic vibration combined with controlled impact energy to plastically deform the surface layer of metals, refining grain structure and reducing residual stress.
Unlike traditional shot peening or thermal stress relief methods, this ultrasonic impact system delivers high-frequency micro-hammering energy directly to the material surface, enabling deeper stress redistribution without excessive material removal or thermal distortion. It is widely used in welding reinforcement, fatigue life improvement, and high-stress industrial component treatment.
The system is equipped with a 20kHz high-power ultrasonic transducer and impact peening gun, delivering controlled mechanical impact at ultrasonic frequency for continuous surface treatment.
A key advantage is its ability to generate deep compressive residual stress layers, significantly improving fatigue resistance and crack propagation resistance in welded and machined parts.
Compared with traditional shot peening, this ultrasonic impact method provides more precise energy control and localized treatment, avoiding surface contamination from steel shots or abrasives.
The process combines mechanical impact + ultrasonic vibration synergy, resulting in refined grain structure and improved metallurgical properties of the surface layer.
It is highly effective for post-weld treatment, eliminating welding residual stress and reducing the risk of stress corrosion cracking.
The handheld design allows flexible operation on complex geometries, large structures, and in-field maintenance applications.
