A method for joining studs to workpieces, in particular for the purpose of stud welding, comprising the steps of acquiring a distinguishing dimension of a stud to be joined by the application of a sensing element to the stud and through measurement of a travel distance of the sensing element as it is applied to the stud; and then joining the stud to a workpiece, if the dimension of the stud is within an allowable tolerance range, and the allowable tolerance range is adapted in dependence on the travel distance of the sensing element measured during a preceding method step.

Joining method and joining appliance

Proposed is a joining system () as well as a method of operating a joining system () for joining elements () onto components (), in particular for the short-time arc welding of elements (), such as metal studs (), onto components (), such as metal sheets (), having a central unit (), which comprises a control device () and connectable to which is at least one joining unit () from a selection of different joining units, each of which comprises at least two modules (). The control unit () is designed so as to recognise (S, S) the mutual compatibility of the at least two modules () of a connected joining unit () as well as the compatibility of the connected joining unit () with the central unit ().
