Specifically, the LZH team is investigating the flow behavior for laser beam welding of similar and dissimilar joints made of aluminum alloys and steel materials. How exactly gravity affects metallic molten pools is what the researchers want to investigate in the Einstein Elevator. Among other things, vacuum conditions, radiation, and electric and magnetic fields cause materials and processes to behave differently. And instead of replacing entire assemblies, existing equipment could be flexibly expanded, modified, or repaired, say the LZH team.Įinstein Elevator at Leibniz Universität Hannover.In space, many conditions for laser beam welding are different from those on Earth. One solution to this problem could be laser beam welding, which could be used to join add-on parts or spare parts together directly on site.
This takes up cargo space and leads to high fuel costs. To equip space stations, fully assembled assemblies currently have to be transported into space. Experiments at the Einstein Elevator at Leibniz Universität Hannover (LUH) are expected to provide important new insights (see below). LZH scientists are investigating the influence of gravity on laser beam welding processes. Furthermore, the Wissenschaftliche Gesellschaft Lasertechnik (WLT) and its members as well as industry partners have put together an application-oriented lecture program on current trends in the field of laser material processing ( click here for the program, in German). In two presentations, LZH scientists will discuss the latest developments in laser-based additive manufacturing with glass (Tuesday, June 21 at 11:30 a.m.
The LZH will also be demonstrating how “smart” agricultural technology of the future can work and will present a laser-based process for sustainable and herbicide-free weed control. At LASYS, LZH will present a modularly-controllable laser head for joining plastics.At this year’s LASYS expo, taking place between 21-23 June in Stuttgart, Germany, Laser Zentrum Hannover (LZH) is to show some of its latest innovations from plant and system technology and developments in the field of lightweight construction.Īmong other items, the LZH will present (on its booth in hall 4, stand A19) individual complete solutions for processes and systems from laser material processing using selected laser processing heads.Īnother focus is on the potential of smart additive laser manufacturing.
