Abstract

Remote joining by plastic deformation in the process of linear flow splitting combines forming withsimultaneously activated joining processes. While the forming process takes place in one region of a pro-file, the joining of the profile with another component occurs outside the forming zone. This approachpromises a great potential with regard to joining multi-material units in a short process chain. Linearflow splitting is a rolling process which results in thin-walled and branched parts out of flat sheet metalswithout any heat treatment. As in other forming processes, residual stresses remain in the manufacturedparts. They are used in the study at hand for a mechanical joining of the profile with other components.Based on numerical and experimental results, two models of joining mechanisms based on spatiallydistributed, uniaxial tensile and compressive stresses are presented and verified. The remote joiningapproach described in this paper accommodates two challenges of modern manufacturing: On the onehand, the increasing market demands for lightweight products which lead to various material combi-nations and hybrid structures in complex assembly units; on the other hand, the need for continuousoptimization of process chains with regard to efficiency.
