| Research Abstract |
Dissimilar materials joining is required in many industries. However, it is difficult to obtain the joint with higher reliability on its strength due to the problems on materials science, processing and mechanics. In this study, effects of formation of intermetallic phase at the interface and weld pool shape on strength of the joint were studied. In order to investigate particularly the effect of weld pool shape, experimental consideration by using the model joints and FEM analysis have been done.
