In this study, the effect of welding fabrication conditions on mechanical properties of weld metal is investigated by experiment and numerical analysis by FEM. The cooling time of welding metal is taken up among the factors which affect the strength of weld metal. Experiment was performed as a parameter heat input, interpass temperature and plate thickness which affects the cooling time, and tensile coupon tests were carried out to clarify relation between each factor and strength. Numerical analysis was performed to investigate the cooling time of the weld metal, and relation between each factor and cooling time was clarified. It is shown that the strength of weld metal can calculate with sufficient accuracy using cooling time.
