Abstract
In the paper, practical aspects of hybrid adhesive-welded joints are described. For the joints made of low-alloy car-body sheet steel HS340LA 1.2 mm thick at selected variable process parameters, a wide range of destructive and non-destructive tests was carried-out. The joints were made using three constructional adhesives, one of those dedicated for hybrid joints. For this adhesive, the most favourable hardening conditions were established. Quality analysis of hybrid joints was based on ultrasonic testing with use of an RSWA (Resistance Spot Weld Analyser) device, metallographic examinations, basic mechanical testing and tests at complex stress state, visual testing with a high-speed camera. Results were compared with adhesive bonding and spot welding. The whole research is summarized with conclusions drawn on the grounds of experimental and analytical results.
