  text: The rapid advancement in the electrification of modern vehicles has led to
    a continuous increase in electrical consumers for various comfort and safety functions.
    Ground studs serve as the electrical interface between the conductive vehicle
    body and the onboard network. Drawn arc stud welding is an economical and established
    joining process for producing ground stud joints. The circuits in the onboard
    network are increasingly subject to greater demands regarding current-carrying
    capacity and long-term stability. Reliable signal and power transmission require
    minimal contact resistance at the electrical connection points of the ground stud
    system and must withstand various operating and environmental conditions over
    the entire service life. In this study, a ground stud made of AlMg5, with a ZnNi-coated
    steel cap nut was used on a 2.0 mm thick sheet of AlMg3. The electrical connection
    of the ground studs was made using tinned copper cable lugs and 35 mm² cables.
    To analyze the electrical resistance behavior in an accelerated test, the ground
    studs were subjected to a superimposed load with a cyclic current profile for
    1008 hours under changing climatic conditions. The results show that under the
    chosen operational and environmental conditions, accelerated aging and intermittent
    resistance behavior occur. A characteristic drop in resistance during the test
    indicates the failure point of the electrical connection. The cause of failure
    can be attributed to media penetration into the electrical contact zone. A failure
    of the electrical connection was observed after 512 hours.
