Improving Fatigue Strength of Welded Joints by Ultrasonic Impact Treatment
Enhancement in fatigue performance of welded joints by Ultrasonic Impact Treatment (UIT) was evaluated with large-scale rolled beam and built-up specimens having yield strength of 345 to 760 MPa. Eighteen rolled-beam specimens having welded details at cover plates and transverse stiffeners and eight built-up specimens having only transverse stiffener details were fatigue tested after treating t...
متن کاملFatigue Strength Assessment of Welded Joints by Using Notch Stress Approach
The fatigue strength assessment of welded joints by using the known parent material fatigue strength is considered in this paper. The stress concentration factor was determined performing FEA of singlesided transverse attachment joints for mean value of weld toe radius which was calculated by using several measurements of the weld toe radius along the weld length. The fatigue strength of welded...
متن کاملFatigue Life of Repaired Welded Tubular Joints
In this study, the effect of repair on fatigue life of tubular joints is investigated. Six cracked specimens precedently subjected to fatigue loading undergone to weld repair. Two of those specimens were shot peened before primary fatigue loading. It is shown that repair gives rise to about 150% increase in fatigue life for original specimens while the increase of fatigue life for shot-peened ...
متن کاملRelation between Residual Stress and Fatigue Strength for Electron Beam Welded Joints of Sheet Metal
Residual stresses in welds significantly affect the fatigue strength and stress corrosion crack resistance of the weld joint, and therefore, numerous studies have been made about the effects. The residual stress induced by electron beam welding (EBW) has also been researched in various approaches, but many of the study reports dealt with thick plates (50 mm or thicker) only.1–5) This was becaus...
متن کاملInvestigation of the Fatigue Strength of the Welded Joints Treated by Tig Dressing
The fatigue fracture of structural details subjected to cyclic loads mostly occurs at a critical cross section with stress concentration. The welded joint is particularly dangerous location because of sinergetic harmful effects of stress concentration, tensile residual stresses, deffects, microstructural heterogeneity. Because of these reasons many methods for improving the fatigue resistance o...
