抄録

In our previous study, it was shown that the fatigue life of the boxing fillet welded joint was enhanced by about 10 times by applying the elongated bead welding with 40 mm bead length to the welded joint by using low transformation temperature (L.T.T.) welding material. 　In this study, the followings were discussed, ① The estimation of the residual stress distribution of boxing fillet welded joint to which the elongated bead welding with L.T.T. welding material was applied, ② The work load and time of elongated bead welding on site welding, ③ The fatigue life enhancing effect of two elongated bead welding joints using different L.T.T. welding materials, L.T.T. 10Cr-10Ni filler metal (LTT1) and L.T.T. 6.5Mn filler metal (LTT2), ④ The fatigue life enhancing effect by using LTT2 with and without elongated bead applied to repair welding of boxing fillet welded joint with fatigue crack, ⑤ The fracture toughness of weld metal with LTT1 welding material, and so on.
