Welded structures subjected to fatigue Loads-5

 

      

Examination of a welded joint under a microscope shows that there are always dis-

continuities, particularly in the transition between the parent metal and the weld. Defects

can be such as undercutting, overlaps, overrunning welds, micro-cracks, excessive con-

vexity etc. Together with these 'micro-geometric' potential stress concentrations, the

'macro-geometric' stress concentrations for example in the form of such features as

sudden changes in the cross sections, determine the fatigue strength of the welded joint.

With a little experience and some imagination, it is soon quite easy to see where fatigue

                cracks might be likely to occur in welded joints.
