Wetting Process during Laser Brazing of Aluminum Alloys with Aluminum-Based Braze Material

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.

High-Speed Visualization of Flux Coated Electrode Hand Welding

The Institute of Materials Science at the Gottfried Wilhelm Leibniz University Hanover, Germany studied electrode hand welding. The burning behavior of that electrode was used as a reference to study the behavior of other commercially available electrodes but also to study the behavior of electrodes from own development projects.
