Ultrasonic Impact Gun UIT Machine for Compressive Residual Stress
Designed to significantly improve and extend the life cycle of industry assets, Ultrasonic Impact Technology (UIT) is instrumental in mitigating tensile stress in heat-effected zones in the mining sector
Ultrasonic Impact Technology treatment is an electromechanical process where ultrasonic energy is converted into mechanical energy.
When UIT is applied to metals and fabricated structures, the process imparts residual compressive stresses, mitigating harmful tensile stress along with modifying grain structure. It can be applied manually or automated depending on the environment which the technology is required to operate in.
The UIT system is an electromechanical process where ultrasonic energy is converted into mechanical energy. When applied to metal fabricated structures, UIT imparts compressive residual stress, mitigates harmful, flexible stress, modules weld toe geometry, and improves grain structure.
UIT delivers an alternative to other methods of peening to modify weld toe geometry and impart beneficial compressive residual stress. Upon application of UIT to the weld toe, the weld toe geometry is modified creating a fatigue friendly geometry.
Compressive residual stress is imparted into the heat affective zone (HAZ) improving grain structure and strength.
A number of research projects indicates that UIT method can increase the fatigue strength of steel welding joint by 60~180%, prolong fatigue life by 10~135 times. It also leads Ti Al welding joint to increase fatigue strength by 26~48% and fatigue life by 5~54 times.
RPS-SONIC Ultrasonic impact treatment machine is composed of ultrasonic transducer with cover, booster, horn, needle and generator.
