The objectives of the current research programme were aimed at investigating the influence of adhesive type and thickness on the available welding parameter tolerances in weld bonding, and determining the mechanism of weld formation and how this is influenced by adhesive type and pre-squeeze conditions. In addition, the mechanical properties of spot welded, adhesive bonded and weld bonded joints were compared under both static and dynamic conditions of loading. The results show that for weld bonding, a paste adhesive type is preferred which will move out of the area between the welding electrodes when the electrode force is applied yet not flow out of a vertical joint before or during curing. Adhesive pastes of viscosity up to an extrusion time of 2000 s for a standard weight of adhesive can be welded through. Overall, therefore, these results show that the incorporation of the spot weld into an adhesive bonded joint can lead to a considerable improvement in joint performance.
