High Quality Handheld Type Ultrasonic Impact Gun/stress Relief Equipment Ultrasonic Impact Treatment

Handheld Type Ultrasonic Impact Gun/stress Relief Equipment

An ultrasonic impact gun is a surface treatment tool that uses ultrasonic vibration to deliver high-frequency, low-amplitude impacts to material surfaces.Core Working Principle. It converts electrical energy into ultrasonic mechanical vibration via a transducer.The vibration is amplified and transmitted to an impact head, which delivers rapid, repetitive impacts to the target surface.The impact frequency typically ranges from 20 kHz to 40 kHz, far higher than traditional impact tools.

The ultrasonic drive power supply is connected to the ultrasonic transducer housed inside the casing via a cable. The transducer's vibration output end is connected to an amplitude transformer, the end of which is equipped with an impact pin. The ultrasonic drive power supply converts mains power into high-frequency, high-voltage alternating current, which is then supplied to the ultrasonic transducer. The transducer then converts the input electrical energy into mechanical energy, i.e., ultrasound, which manifests as a longitudinal reciprocating extension and retraction motion. The frequency of this motion is equal to the frequency of the AC current from the drive power supply, and the displacement is approximately tens of micrometers. The amplitude transformer serves two purposes: first, it amplifies the transducer's output amplitude to over 100 micrometers; second, the impact pin applies impact force, propelling it forward at high speed. After impacting the workpiece, the energy is transferred to the weld seam, thus relieving internal stress. The impact head rebounds after being reacted to by the workpiece, and upon encountering the high-frequency vibrating amplitude transformer, it is re-excited and impacts the weld seam at high speed again. This process is repeated multiple times to complete the impact operation.

Key Functions & Applications

Improve material performance: Reduces surface roughness, eliminates residual tensile stress, and introduces compressive stress to enhance fatigue resistance.Weld quality optimization: Refines weld seam structure, eliminates weld defects (e.g., porosity), and improves weld strength and durability.Common scenarios: Used in aerospace, automotive manufacturing, marine engineering, and metal structure maintenance (e.g., aircraft components, ship hulls, pressure vessels).

Advantages

Low energy consumption and minimal noise compared to conventional impact tools.
Precise control over impact intensity and area, avoiding excessive material deformation.
Enhances surface hardness and corrosion resistance without changing the material's chemical composition.
The core benefits of using an ultrasonic impact gun for surface treatment lie in improving material durability, optimizing surface quality, and ensuring processing precision with low costs.

Key Benefits

Enhances fatigue life and structural reliability: Eliminates residual tensile stress on the surface (a major cause of cracks) and introduces beneficial compressive stress, significantly improving the material’s resistance to fatigue and corrosion.
Optimizes surface and internal quality: Refines the surface microstructure, reduces roughness, and eliminates micro-defects (such as porosity, microcracks) without damaging the base material.

High precision and controllability: The high-frequency (20–40 kHz) low-amplitude impact allows precise control of the treatment area and intensity, avoiding excessive deformation even for thin-walled or precision components.
Efficient and cost-effective: Works faster than traditional manual or mechanical treatment, with low energy consumption, minimal noise, and no need for post-processing (e.g., grinding), reducing overall production/maintenance costs.
Wide adaptability: Suitable for various metals (steel, aluminum, titanium, etc.) and complex structures (weld seams, curved surfaces, narrow spaces), compatible with aerospace, automotive, marine, and other high-demand fields.

The function of the ultrasonic Impact gun:

1. Ultrasonic aging treatment can significantly improve the fatigue life and fatigue strength of welded joints. Post-weld treatment of the weld toe smooths the transition, reducing stress concentration caused by weld reinforcement, eliminating surface defects, and simultaneously inducing significant compressive plastic deformation at the weld toe, generating residual compressive stress, adjusting the residual stress field, and strengthening and hardening the weld toe area.

2. As a post-weld treatment device, ultrasonic impact equipment can simultaneously improve multiple factors affecting weld quality, such as stress, defects, weld toe geometry, and surface strengthening. Therefore, it has a multiplier effect on improving the fatigue performance of welded joints, increasing fatigue strength by 50%-120% and extending fatigue life by 5-100 times.

3. Using an ultrasonic treatment gun eliminates the need for traditional grinding and slag removal processes, saving 20% ​​of labor time, reducing labor intensity, and improving production efficiency.

sale the right products instead of the expensive one

Rps-sonic, consisted with a couple of young people who love ultrasonic very much.The founding members of RPS-SONIC have an average degree of Bachelor's degree or above. They have been in the ultrasonic industry for more than 5 years and have rich experience in ultrasound. The company's business philosophy is: Do not blindly promote any product, find the right product for the customer. So before each order, we will confirm all the details, including application details, equipment conditions, equipment specific information.

And we have the Professional import and export company， HangZhou LanBen Trade Co., Ltd, can export to any country wordwide.

Before year 2012, we only sale second branson / dukane / rinco / herrman/telsonic welding equipment , during these twenty year develop, we find, more and more people have problem with the core part of ultrasonic welding equipment -generator and transducer, so we decided to start our business of transducer and generator of our own transducer and generator. Many of the end user meet the transducer problem, they don’t know why transducer broken, and changing the expensive transducer one by one. Actually, one branson /dukane /rinco transducer can use 10~30 year, even the cheapest transducer can use about 5 years. So there must some reasons if your transducer broken in one year. That’s why we want build Rps-sonic, we need to help more end user to know more about transducer , to use ultrasonic equipment better, to save cost when meet problem.

The same to generator, Unreasonable operation may shorter the use-life of ultrasonic generator. So we have to make technical inquiry before operate ultrasonic welding machine. The key point of ultrasonic machine is resonance, only keep every part in resonance can make the system in best work environment.

Till now , we still have a lot of Branson /dukane/ rinco/ herrman telsonic welding machine, so that we can confirm every transducer/generator we made can matching to the original machine.

Of course we can make the transducer/generator replace for Branson /dukane/ rinco/ herrman telsonic welding machine, we can also make transducer/generator for any application of your ultrasonic equipment. We supply OEM service for oversea customers, we already have OEM customer in USA and German.

If you have any problem in ultrasonic area, welcome contact Rps-sonic.
