Abstract:	近年來核電廠中發現多例異材焊接部位出現應力腐蝕裂縫，裂縫成長之主因為焊接殘留應力，因此對焊接殘留應力之評估成為提高可靠度之必要操作，本文發展出3D與2D軸對稱之有限元素分析模型與計算流程，建立焊接殘留應力之評估技術，並與EU模型進行驗證獲得精確之結果，此外同時進行焊接參數對殘留應力之敏感度分析。 Recently the stress corrosion cracking cases of dissimilar metal welds are found in many nuclear power plants.Weld-induced residual stress is main factor for crack growth. Therefore exact estimation of residual stress is important for reliable operation.
