Abstract
⺠Identification of two types of undercuts in two cases, remaining or removed mill scale (oxides). ⺠With remaining mill scale, the oxide caused lack of fusion defect. ⺠Formation mechanisms of the two kinds of undercut are observed by high speed imaging. ⺠In case of mill scale, imaging showed that the melt does not attach to the top but glides down. ⺠A base material layer is the interface for rounded undercut formation.
