Videographic Data for Pore Formation and Melt Pool Analysis of Laser Welded Al-Cu Joints using Synchrotron Radiation

The published data include video recordings of synchrotron radiation during a laser beam welding process in aluminium-copper joints. The recordings show the phase boundaries of the materials and are suitable for an analysis with regard to material mixing and pore formation. The experiments were conducted with the high energy beamline P07 (EH4) of Petra 3 at Deutsches Elektronen Synchrotron DESY in Hamburg, Germany.
