Laser Deposition Welding Machine

• Subject Area: Mechanics and Constructive Mechanical Engineering
• Term: Funded in 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 428364048

In compliance with the strategic orientation of Paderborn University in the field of hybrid lightweight construction and the development of new alloys for the production of geometry-adapted and weight-optimized components, the Chairs of Automotive Lightweight Design (LiA), Materials Science (LWK) and Forming Technology (LUF) are applying for the laser deposition welding system described hereafter.The main objectives pursued with the system applied for, are the development of innovative and novel applications in automotive lightweight construction, e.g. in the form of multi-material components (metal-metal hybrids) or technology hybrids, by further processing already formed geometries (e.g. sheet metal or thin-walled profiles). Furthermore, research on novel tools or tool inserts, e.g. with near-contour and locally variable cooling in hot-forming or injection moulding processes (for example with variable copper contents within steel-copper hybrids) will be studied to develop more efficient processes. Here, in particular process-microstructure-property correlations have to be considered. Furthermore, detailed parameter studies and material characterizations in the field of medical technology are targeted. Overall, the proposed system will be integrated into a cross-linked process chain and will generate further synergy effects with upstream and downstream systems in the sense of Industry 4.0.The research foci and competences of the three participating chairs complement each other in a perfect way. The research activities of the Chair of Automotive Lightweight Construction range from conception and design to calculation and simulation to the experimental investigation of lightweight construction components. The focus of the Chair of Materials Science is on the investigation of the interrelationships between the process parameters of manufacturing processes, the microstructure produced by these processes and the resulting material properties. The research focus of the Chair of Forming Technology is the investigation and design of processes, tools and machines for the flexible and efficient production of components from sheet metal and profiles.
