Product Name:Ultrasonic Stress Relief Machine
Product Introduction :Ultrasonic impacting is utilize high-power ultrasonic drive impact tooling impact on surface of metal work piece as more than 20,000 time per second, because maco- power caused by ultrasound’s high frequency,the surface of metal will disformed; meanwhile, ultrasonic impacting changed original stress field, can produced a certain value pressure stress, make the ultrasonic impacted part get to strengthen.

► Core technology of ultrasonic stree relief equipment:

■Make residual tensile stress in the surface of weld seam inside into pressure stress, and significantly raising fatigue life of metal structure, releasing the residual stresses effect can reach more than 80%;
■Changing metal grain structure in the surface inside, make it plastic deformation layer, and make metal surface layer’s strengthen & rigidity has significantly improve, improve strenthen 50-100%, fatigue life improve 5~80 times than before;
■Change weld toe’s shape, reduce streess concentration;
■Change welding stress field, reduce the welding disformation significantly, improve stability of tooling dimension.

►Ultrasonic stree relief equipment application:

ultrasonic stress relief equipment used for the industries that has high requirements on welding seam’s stability and strengthen, such as metal treatment of bridge, electric power, ship building, pressure vessel, steel structure etc.
