Résumé des résultats (Abstract) (Anglais)

Cryogenic spray cooling with dry ice allows to increase productivity and material efficiency in laser deposition brazing of lead-free white metal by factor five. Overheating and undercooling are prevented by temperature measurement and predictive closed-loop control.
