  • Fatigue Life Improvement of Tubular Welded Joints by Ultrasonic Peening .(pdf)
    is based on the combined effect of the high frequency impacts of the special strikers and ultrasonic oscillations in treated material. The UP was applied successfully for increasing the fatigue life of parts and welded elements, eliminating of distortions caused by welding and other technological...
  • Application of Ultrasonic Peening for Fatigue Life Improvement of Automotive Welded Wheels
    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...
  • Portable Hardness Test Technology for Assessing Titanium Weld Quality (.pdf)
    procedures. The OE relationship for Rockwell B hardness was used to calibrate the portable hardness test procedure. The portable hardness tester was based on using the ultrasonic contact impedance method. This study has shown that with careful attention to detail, portable hardness testing can be used...
