Influence of Magnesium on Spatter Behavior in Laser Deep Penetration Welding of Aluminum Alloys
Journal of Manufacturing and Materials Processing, 2019 The quality of welds, as well as the necessity of post-processing, is challenged by spatter generation during the laser keyhole welding process. In this study, the influence of the magnesium content on spatter behavior is studied for three aluminum ...

Spatter matters-distinguishing primary (eruptive) and secondary (non-eruptive) spatter deposits [PDF]
, 2018 Spatter is a common pyroclastic product of hawaiian fountaining, which typically forms vent-proximal ramparts or cones. Based on textural characteristics and field relations of spatter from the 1969 Mauna Ulu eruption of Kīlauea, Hawai’i, three spatter ...
