Effect of Welding Angle on Fatigue Performance of Welded Structure
The effect of welding angle on the stress distribution of the welding zone was analyzed.The fatigue life of the weld structure was determined by normal stress approach.The results show that a bigger welding angle induces a more severe stress concentration,which reduce greatly the fatigue life of the welded structure.The fatigue life of the welding structure exhibits an exponential decay function of the welding angle.
