Abstract:
Joints which are solely produced by forming processes are capable of transmitting e.g. axial loads by means of dominating force- (alternatively named interference) or form-fit. Furthermore, a transmission of load could be directed by a combination of both and with supporting adhesives. Joining by forming has been done by compressing tubes using external rolling and electromagnetic forming; joining by expansion has been performed by dieless hydroforming and rolling. Moreover, a problematic constraint for joining by expansion or compression, namely joining of identical materials, which is a topic of a current research project within the scope of SFB/Transregio 10, has to be taken into account. Consequently, the article focuses on the feasibility of combining joining by forming processes and adhesives for joining of tubular workpieces made of identical material (EN-AW6060F22). Resisting loads of form- and force-fit joints have been taken as a reference.
