The Effect of Ultrasonic Peening Treatment on Fatigue Performance of Welded Joints. [PDF]
Ultrasonic peening treatment (UPT) as a method of severe plastic deformation was used to treat cruciform welded joints of Q345 steel. The application of UPT achieves material surface nanocrystallization of the peening zone, reduces stress concentration, and produces residual compressive stresses at the welded toe.
