Expert Group: Joining Technologies
The Joining Technology Expert Group is an open and interdisciplinary working and communication platform at the ILK, which develops customer-orientated solutions for application-specific problems in the field of joining technology.
In the conception, design and dimensioning of lightweight structures, the provision
of suitable joining systems has a decisive importance. The aim of our Expert Group is to identify the relevant problems in the field of joining technology at an early development stage especially with regard to multi material design. Based on this, application-oriented joining solutions are identified and investigated scientifically. For this purpose, both established technologies are considered and applied to specific joining tasks as well as novel material-adapted joining methods are developed. The Expert Group pursues a holistic, material-independent development approach. It includes the technological
basics, the material-structural phenomena in joining zones and the modelling of both the joining process and the load-bearing behaviour.
One main research focus are intrinsic joining zones, which are formed in hybrid structures during component manufacturing: e.g. when overmoulding laser-structured or plasma-treated surfaces. Extrinsic joining zones, which enable the integration of hybrid structures into the system environment, are another focal point: e.g. the novel joining process Hotclinching. In addition, we develop novel methods for the analysis and description of the local composite material structure in joining zones for the design and dimensioning of
joining systems: e.g. for inserts embedded by warm forming.
