Abstract

The present invention relates to a process for checking the suitability of a connection between at least two plate-like components consisting of the following stages: registering a number of acoustic signals during a cold reforming joining process for connecting at least two plate-like components; processing the acoustic signals; evaluating the acoustic signals by means of suitable software and hardware and emitting a corresponding signal.
