Because of the enormous forces that are necessary for the processing, the processing plants must be massively dimensioned , The self-piercing rivet joints themselves are highly susceptible to cracking and pose a safety risk. The cracks are in the plates, sheets or the like to be joined. In addition to the question of a secure connection, the question of corrosion protection also arises, in particular at the locations subject to cracking. The detection of these cracks is hardly possible with today's metrological possibilities, for example with eddy current testing devices, since there are too many interfering signals at the location of the punched rivet connection.
