YP-Y25 Ultrasonic Aging Treatment Of Metal(UIT)

Ultrasonic impact is the use of high-power ultrasound to promote the percussive tools to more than twenty thousand times per second, the frequency of the impact of the metal surface, due to the high-frequency, high efficiency and focus ultrasonic energy to the metal surface to produce a larger pressure plastic deformation;ultrasonic shock waves to change the original stress field of a certain value, the compressive stress; ultrasonic impact site can be enhanced.
Ultrasonic drive power cable and set within the casing of the ultrasonic transducer is connected transducer vibration output end of the horn connections horn end is equipped with impact pin.
Ultrasonic drive power electricity is converted into high-frequency high-voltage alternating current, lost to the ultrasonic transducer. Ultrasonic transducer will then convert the input electrical energy into mechanical energy, ie, ultrasound, its manifestations is the transducer in the vertical reciprocating telescopic movement; the telescopic movement frequency equal to the power of the drive frequency of the AC current, the stretching of the displacement of more than ten microns. First, the role of the horn transducer output amplitude amplification, reach more than 100 microns, the other hand, the impact of the needle to exert impact, and promote the impact of high-speed needle pediment. The impact of needle impact the workpiece, the energy is passed to the weld in order to achieve the elimination of internal stress. Rebound after impact head by the reaction of the workpiece, and met the high-frequency vibration of the horn are excited again, and again high speed and crashed into the weld, so repeatedly, the completion of the impact of job.

Effect

1 .Cause residual stress of pulling in the metal welding line surface layer changed into compressive stress. Significantly increase the fatigue life of metal structure.

2. Change the grain layer on metal surface into plastic deformation layer to improve strength and hardness of metal surface layer significantly.

3. Improve the weld toe geometric, reduce the stress focus.

4. Change weld toe stress field, reduce welding deformation obviously, and improve size stability of work piece.

Application

Ultrasonic impact treatment device application areas: the industries have strict requirement on welding stability and strength. Such as bridge, electric power, shipbuilding, pressure vessel, steel structure and other industry’s metal welding.
