Hagenlocher, Christian, 2022, "Python implementation of heat accumulation equations for additive manufacturing", https://doi.org/10.18419/darus-2609, DaRUS, V1
This is a python implementation of the heat accumulation equations, which describe the increase of the residual temperature in additive manufacturing. The Derivation of the equations is described in the related paper given below. If you run the script in the console, it creates t... |
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; Boley, Steffen, 2022, "Infrared imaging of laser based direct energy deposition of AlMg5 wire", https://doi.org/10.18419/darus-2242, DaRUS, V1, UNF:6:hJjhqJEMD0Y6k8xQqETXMw== [fileUNF]
The data shows temperature fields, which were recorded during laser-based direct energy deposition of AlMg5 wires by means of infrared imaging. All captured temperature fields are given as sequences of csv data. Each frame of the acquired image sequences is represented by its ind... |

Wagner, Jonas; Hagenlocher, Christian; Fetzer, Florian; Böhm, Constantin; Weber, Rudolf; Weihe, Stefan; Graf, Thomas, 2021, "Replication Data for: Numerical Analysis of the Local Solidification Conditions in Laser Beam Welding of Aluminum Alloys", https://doi.org/10.18419/darus-2106, DaRUS, V1
The here published experimental data was done in a collaborative DFG project between IFSW and MPA (project number 398552773). The published data is replication data for a publication. The data show high-speed videos of full-penetration laser beam welding of the aluminum alloy EN... |

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... |
Böhm, Constantin; Hagenlocher, Christian; Wagner, Jonas; Graf, Thomas; Weihe, Stefan, 2021, "Replication Data for: Analytical Description of the Criterion for the Columnar-To-Equiaxed Transition During Laser Beam Welding of Aluminum Alloys", https://doi.org/10.18419/darus-2075, DaRUS, V1
The here published experimental data was done in a collaborative DFG project between IFSW and MPA (project number 398552773). The published data is repilcation data for a publication. In this project laser beam weld trials were conducted and the resulting weld seams were prepared... |

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... |
