Distribution of microstructures in weld heat affected zone of multi-pass welded steel has large effect on, toughness of welded joints. Therefore, the method to estimate this distribution and the application of this method were investigated in this study. Main results obtained are as follows. At first, the imaginary centers of heat sources were obtained using the contour of fusion line of actual welded joint. And the sequence of peak temperatures at some point of heat affected zone was calculated using heat conduction equation. Then, the microstructure of this point was estimated using the results obtained previously.　Finally，　the　S’raction　of　low　toughness　microstructure　was　obtaied　using　this　method．
