The paper presents the results of testing the joints of unequal materials using flow-drill technology and a combination of flow-drill technology and adhesive bonding. The formed joints were tested by tensile and shear test according to ISO 12996. The positive effect of adhesive bonding on the load-bearing capacity of the joints and on the stress distribution in the tested materials was observed.

The paper provides an overview of the load-bearing capacity of joints of the same and unequal thin steel sheets formed on different pretreated surfaces by adhesive bonding. Four types of surface preparation and rubber-based adhesive were tested. The joints were subjected to a climatic test according to VW: PV1200. The change in the load-bearing capacity of the joints was evaluated on the basis of the force at the joint failure, the type of failure and on the basis of the load to displacement ratio.
