    Abstract: According to a first embodiment of the method, the stud holder is first positioned without a part to be welded at a certain distance from the tool surface. A part to be welded is then provided. When the welding axle moves towards the workpiece, the path that needs to be travelled in order to bring the part to be welded and the workpiece into contact is detected. Conclusions regarding the presence or absence of a part to be welded are then drawn, based on the previous distance between the stud holder and the workpiece and the path travelled. According to another embodiment, the stud holder is moved towards the workpiece with a part to be welded until contact is detected. If, after contact is detected, further movement of the welding axle is possible as a result of the part to be welded being pushed into the stud holder, this is interpreted as an indication of the presence of a part to be welded.
