Joining in Car Body Engineering 2025
Every year in April, the three-day Automotive Circle conference on Joining in Car Body Engineering, held in Bad Nauheim, Germany, presents recent supplier innovations, latest OEM application reports (accompanied by car body exhibits, whenever possible) and new, application-oriented academic studies, discussing progress and latest trends on all aspects of industrially relevant car body joining technologies, with an audience of expert automotive engineers from all over the world.
Please note the date: The next Joining in Car Body Engineering conference in Bad Nauheim will take place on April 8-10, 2025.
Conference Structure
The three conference days consist of two, separately bookable modules:
Module 1, covering progress in Adhesive Bonding and Hybrid Bonding technologies, starts on the first conference day and ends in the early afternoon of the second.
Module 2, covering developments in Thermal and Mechanical Joining technologies, starts in the morning of the second conference day and ends in the afternoon of the third.
The first sessions or the second conference day feature a joint program of presentations for participants of either module, with topics that are presumed to be of interest to all participants, for instance OEM presenting the full joining concept of a recently launched car body project.
