溶接残留応力が疲労き裂伝ぱにおよぼす影響を80kg/mm^2級高張力剛を用い, き裂開閉口現象に注目して実験的に検討した. すなわち, サブマージ溶接した縦突合わせ溶接継手試験片と素材試験片における横われを想定した中央切欠きからの疲労き裂伝ぱをしらべ, 溶接景趣試験片における残留応力の影響も素材試験片における応力比の影響も有効応力拡大係数範囲ΔK_<eff>を用いれば統一的な定量的評価が可能であることを明らかにした.

The dissimilar materials welded joints of high manganese non-magnetic steel/carbon steel(hereafter refered to as DMW joints), in which weld defects such as hot crack or blowhole are not found, were the good quality. Tensile strength of DMW joints was 10% higher than that of the base metal of carbon steel. In the bend tests, the DMW joints showed the good ductility without crack. Charpy absorved energy at 0 (℃) of the DMW joints was over 120 (J) in the bond where it seems to be the lowest. Large hardening or softening was not detected in the heat affected zone. Fatigue strength of the DMW joints is almost the same with that of the welded joints of carbon steel/carbon steel. As the fatigue strength of the DMW joints exceeds the fatigue design standard curve of JSSC for carbon steel welded joints, the DMW joints can be treated the same as the welded joints of carbon steel/carbon steel of which strength is lower than that of high manganese non-magnetic steel, from the viewpoint of the fatigue design.
