The combination of resistance spot welding with structural bonding offers a number of advantages over the individual processes, such as improved crash behaviour, higher joint strength under oscillating loads or improved corrosion protection of the joining zone. These are consistently utilised, particularly in the sheet metal industry. In recent years, developments in the automotive and automotive supply industry have led to the increased use of higher and high-strength steel materials in order to reduce the weight of vehicle bodies and increase their passive safety. and increase their passive safety. This research report presents results from investigations into the behaviour of high-strength and high-strength steel materials joined with current and new hot and cold-curing adhesive systems up to a strength of 1650 MPa.
The influences of the welding process on the bonded joining zone and on the mechanical properties of the joint as well as the influences of the adhesives used on the joining process are discussed. The characterisation of the joints with regard to their mechanical properties and their corrosion properties provides the designer with a basis for the use of hot and cold-curing adhesive systems in combination with high-strength and high-strength steel materials. The IGF project 14476 N of the FOSTA-Forschungsvereinigung Stahlanwendung e. V., Düsseldorf, was funded by the Federal Ministry for Economic Affairs and Energy via the AiF as part of the programme for the promotion of joint industrial research (IGF) on the basis of a resolution of the German Bundestag. The project was carried out at the University of Paderborn, Laboratory for Materials and Joining Technology and at the SLV Munich branch of GSI GmbH.
