The development of the Ultrasonic Peening (UP) technology was a logical continuation of the work done before directed on the investigation and further development of known techniques for surface plastic deformation such as shot peening, hammer peening, needle peening. The UP technique is based...

The Ultrasonic Peening (UP) is the most efficient technique for increasing the fatigue life of welded elements as compared to such existing improvement treatments as grinding, TIG-dressing, shot peening, hammer peening, etc. The results of experimental investigation of the efficiency of UP...

The efficiency of Ultrasonic Peening (UP) application for fatigue life improvement of automotive welded wheels was studied based on the results of fatigue testing of real wheels in as-welded condition and after application of the UP. During the fatigue loading, the cracks initiate in the weld toe...

...overloading, ultrasonic peening, etc. As an example of using the ES for residual stress analysis, the results of computation of the residual stress effect on the fa-. tigue life of a transverse loaded butt weld (made in shop in flat position, toe angle ≤ 30°, NDT), depending on the stress ratio. R...

...on the service life of. structural components without having to perform time- and labor-consuming fatigue. tests. The program package enables to calculate the fatigue life of structural. components after application of heat-treatment, vibration treatment, overloading,. ultrasonic peening and other...

...on the fatigue life of welded elements as well as a new technology and, based on it, compact system for beneficial redistribution of residual stresses by ultrasonic peening are introduced. Examples of practical application of the developed engineering tools for residual stress management, directed...

...magnetic, and ultrasonic methods of residual stress measurement are compared. Sources of error arising in practical application are described. Subsurface measurement is shown to be necessary to accurately determine the stress distributions produced by surface finishing such as machining, grinding...

...provide very tight tolerances and dimensional sorting capabilities." The firm employs camera vision technology with parallel processors, and laser and LVDT dimensional sorting devices. Multistage ultrasonic cleaning equipment and a cleanroom environment enable the company's staff to hold 5- um total...
