Wagner, Jonas; Hagenlocher, Christian; Weber, Rudolf; Hummel, Marc; Beckmann, Felix; Moosmann, Julian; Graf, Thomas, 2024, "Synchrotron X-ray video of full-penetration laser welding of aluminum AA1050A", https://doi.org/10.18419/darus-3860, DaRUS, V1
The video shows a synchrotron x-ray video of full-penetration laser welding of the aluminum alloy AA1050A (Al99.5). At the beginning of the video the transition from partial penetration welding with a keyhole which is closed at its bottom to full-penetration welding with a keyhol... |

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... |
