Abstract

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.
