Course content

Joining is recognized as a core element of innovative and sustainable manufacturing. Emerging trends in manufacturing such as light weighting, increased performance and functionality increases the use of multi-material, hybrid structures and the need for joining of dissimilar materials. This corse summarizes state of the art research in joining dissimilar materials. Current and emerging joining technologies are reviewed according to the mechanisms of joint formation, i.e.; mechanical, chemical, thermal, or hybrid processes. Methods for process selection are described. Future challenges for research on joining dissimilar materials are summarized.

Learning outcome

Knowledge about the different joining principles: Mechanical – A joint generated through a mechanical mechanism. Examples include: Screw joining, riveting, clinching, and flanging, sewing, winding, interference fit and gripping through plastic deformation 2. Chemical – A bond formed through chemical reaction. Examples include: Adhesive bonding, adhesive-bolt hybrid joining, potting 3. Thermal – A bond formed through applying thermal energy. This includes fusion and solid state processes, arc welding, brazing, electron beam welding, friction welding, lasers, electrical resistance welding, etc.
