Resumen: Thc fatigue strengths of welded joints are dominated by geometric factors. The influence of geometric factors, particullary the thickness was first predicted by fracture mechanics and then confirmed experimentally. In the case of plates with transverse fillet welds it was been predicted that fatigue strength is govemed not only by tickness but also by attachment size and weld toe radius, although experimental confirmation is relatively limited thus far. For plates with longitudinal surface attachments the situation is not still clear, although the problem is more complicated and require other analysis than merely a consideration of tickness. The effect of parent metal and residual stress on fatigue strength of welded joints is summary considered in this paper.
