Dr. Abuabiah recently conducted a research visit at Fraunhofer IPT as part of the BALSAM project. The primary focus of this one-week visit was to collect data related to various parameters in Laser Wire-Feed metal Additive Manufacturing (LWAM), i.e., laser power, wire feed rate, traverse speed, and welding angle to study their impact on the deposited bead geometry.
In addition, the temperature of the bead geometry was measured while changing the laser power to gain a deeper understanding of the relationship between these two factors. The measurement was taken using a thermal camera, and the laser power was changed over a range of values. The data collected during this process will be analyzed to determine the relationship between temperature and power, which will be critical in designing a controller to improve the accuracy of the deposited beads.
The experiments were conducted using the Wire-Based Laser Metal Deposition (LMD-w) welding head, which was mounted on an industrial robot system. The use of the industrial robot system ensured that the experiments were conducted under controlled conditions, allowing for multiple repetitions and systematic testing of different parameters. This provided a robust and reliable dataset that will be used to design a controller that will improve the accuracy of the deposited beads.
Dr. Abuabiah had the privilege of working with Tizia Weidemann and Stefan Graefe, both renowned experts in the field of metal deposition and welding. This collaboration was incredibly valuable and provided Dr. Abuabiah with valuable insights and knowledge. Dr. Abuabiah is grateful for the opportunity to participate in this research visit and looks forward to continuing this collaboration and making advancements in the field of metal deposition.
