Spatter formation in laser beam welding using laser beam oscillation
Welding in the World, 2014 This paper presents an approach towards a better understanding of spatter formation in laser beam welding. Hereunto, experimental investigations and numerical simulation are carried out. For the study, various steels and aluminium alloys were selected to investigate the influences of alloying elements upon spatter formation.

Correlation of spatter behavior and process zone formation in powder bed fusion of metals
CIRP Annals, 2020 In powder bed fusion of metals by a laser beam (PBF-LB/M) spatters evolve due to evaporation phenomena within the interaction zone of the laser-beam and material. The evaporation is of high importance for the evolution of a melt depression in the process zone.

Study on Temperature Influence on Lack of Fusion Formation in Spatter/Base Metal Interface
Advanced Materials Research, 2014 In the development of modern welded structures with longer life-time and/or higher load-carrying ability, fatigue properties are becoming more and more important. A lot of researches have been done to investigate which factors can elongate the fatigue life of weldments.

Numerical study of spatter formation during fiber laser welding of aluminum alloy
Journal of Manufacturing Processes, 2018 Abstract The weld convection and spatter formation in aluminum alloy fiber laser welding are investigated based on numerical simulation and high speed photography results. It is found that a clockwise flow pattern exists in the rear part of the keyhole.
