Joining in Car Body Engineering 2024
EFFECTIVE JOINING – AND DE-JOINING
Optimising second-generation BEV and PHEV car body structures and moving towards a sustainable, carbon-neutral, yet cost-effective production probably are the two main goals in modern car body engineering, and both have much to do with optimised joining technologies and joining concepts. For instance:
- Modern battery case structures are becoming further integrated into crash load paths: How do joining concepts best reflect that?
- Megacastings are intensely discussed: When realised, how are they best joined to the rest of the structure?
- Carbon-neutral vehicle production scenarios need to include intelligent recycling concepts: Joints may need to be easily de-joinable at a vehicle’s end-of-life.
Thus, to discuss latest suggestions for optimal joining solutions, Automotive Circle’s international conference on Joining in Car Body Engineering will again discuss latest progress in all industrially relevant body shop processes with its network of experts, on April 16-18, 2024, in Bad Nauheim, Germany.
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.
