Finite element simulation, were carried out to study the effect of different weld geometry on the fatigue behavior in a cruciform fillet welded joint. In which, presence of welding residual stresses were considered for evaluating the fatigue behavior of joint. For that 3D coupled analysis was done, in which the temperature filed of transient thermal analysis is considered as thermal load to structural analysis. The fatigue behavior is evaluated under constant amplitude loading (R=0). The aim of this work is fatigue behavior evaluation of fillet welded cruciform joint for different weld geometry. The weld geometry are considered: isosceles triangle, scalene triangle, concave and convex geometries.
