Faure, Frauke; Hagenlocher, Christian; Lind, Jannik; Wagner, Jonas; Weber, Rudolf; Graf, Thomas, 2022, "10 kHz x-ray video of laser beam welding of copper", https://doi.org/10.18419/darus-2086, DaRUS, V1
At the X-ray facility at the IFSW, so far it has been possible to record videos with a framerate of 1 kHz to 3 kHz. In this setup the X-rays propagate through the workpiece and are filmed by the high-speed camera via a projection on the scintilator. Through a new sample formation... |

Hagenlocher, Christian; Lind, Jannik; Wagner, Jonas; Hummel, Marc; Olowinsky, Alexander; Weber, Rudolf; Graf, Thomas, 2021, "Comparison of heat conduction mode and deep penetration mode by means of high-speed synchrotron X-ray videos during laser beam welding", https://doi.org/10.18419/darus-2078, DaRUS, V2
There are two modes of laser beam welding: the heat conduction mode and the full penetration mode. The heat conduction mode is present if the intensity of the laser beam is to low to evaporate but sufficient to melt the irradiated material. This welding mode results in a very sta... |

Lind, Jannik; Hagenlocher, Christian; Blazquez-Sanchez, David; Hummel, Marc; Olowinsky, Alexander; Weber, Rudolf; Graf, Thomas, 2021, "High-speed synchrotron X-ray video of the laser beam cutting process in a 2 mm thick sheet of aluminium", https://doi.org/10.18419/darus-1824, DaRUS, V1
The generation of low surface roughness of the cut edge during laser beam cutting is a challenge. The striation pattern, which determines the surface roughness, can be distinguished into regular and interrupted striations, the latter resulting in an increased surface roughness. I... |
