Honda developing new weight-saving joining technology
…
Honda has announced it is developing a new technology that allows steel and aluminium to be joined in a process that will see vehicle weight reduced.
First used to join a new aluminium outer door panel – conventionally made of steel – to a steel inner door panel, the claimed world-first application allows the two dissimilar metals with different expansion rates to be layered and hemmed together twice to form a ‘3D Lock Seam’ (3DLS) structure.
