The fatigue crack propagation behaviour which propagated on the electron beam weld bead was investigated and its estimation was done by elasto plastic analysis. The fatigue crack propagation rate was increased monotoniously when the crack was remote from the weld bead. The crack coming near the bead, the bead was found to reduce the increment of its rate. On the fusion line, the rate became very small. After the crack came into the bead, the rate was increased again monotoniously. As the crack was coming near the bead, the fatigue crack path was beginning to get inclined to base metal. The weld bead was also found to influence the fatigue crack propagation direction. The fatigue crack propagation behaviour estimated by elasto plastic analysis was in good agreement with the behaviour which was observed in fatigue test.
