On 31 March 2023, the Institut für Strahlwerkzeuge (IFSW) said goodbye to one of its heads into a well-deserved retirement with a celebratory colloquium on the topic of "Scaling of Laser Processes in Manufacturing". Apl. Prof. Dr. Rudolf Weber has been a lecturer and the head of process development at the IFSW since 2008.
In addition to a historical review of the past 15 years by Prof. Dr. Thomas Graf, apl. Prof. Dr. Rudolf Weber and active and former staff, there were four scientific presentations. Prof. Andreas Michalowski (Deputy Director at the IFSW), Prof. Beat Neuenschwander (Institute ALPS, Bern University of Applied Sciences), Dr. Simon Olschok (Welding and Joining Institute, RWTH Aachen University) as well as Prof. Dr. Arnold Gillner (Chair of Laser Technology, RWTH Aachen University) not only had exciting and humorous technical presentations in store, but also personal and touching words for Ruedi Weber. At the subsequent reception in the halls of the IFSW, the guests from research, industry and science were able to enjoy a wonderful evening and discuss the whole range of topics from the past 15 years.
