The Bremer Institut für Angewandte Strahltechnik - BIAS studied the wetting behavior in laser brazing. To reveal periodic melt pool propagation effects that occur during laser brazing of aluminum, and for a better understanding of those effects in laser brazing in general, the researchers analyzed high-speed recordings of the brazing process with aluminum alloy.
