Abstract: The welding device for connecting welding elements (2), comprises a workpiece (4) by a welding process, which comprises providing a welding element-holder (6) for holding the welding element, and providing a drafted-element (8) for drafting on the workpiece, where the welding element-holder is movably arranged relative to the drafted-element. A detection- and signal element (10) are formed in addition to record a position of the welding element-holder relative to the drafted-element and to produce a signal, which contains an information about whether the recorded position. The welding device for connecting welding elements (2), comprises a workpiece (4) by a welding process, which comprises providing a welding element-holder (6) for holding the welding element, and providing a drafted-element (8) for drafting on the workpiece, where the welding element-holder is movably arranged relative to the drafted-element. A detection- and signal element (10) are formed in addition to record a position of the welding element-holder relative to the drafted-element and to produce a signal, which contains an information about whether the recorded position lies inside or outside of a defined position target range. A block- and release element are construed in addition to block or to release a trigger of the welding process, where the block- and the release elements are formed in such a way that the detection- and the signal elements are connected that it blocks the trigger of the welding process. The position is recorded with the detection- and the signal elements lie outside the position-target range. The detection- and the signal elements comprise a switch, a mechanical switch or a hall-sensor for detecting the position. The welding element-holder is arranged relative to the drafted-element in such a way that it occupies a resting position when no external forces act on the resting position. The detection- and the signal elements comprise a distance-measuring device for recording the position, where the distance-measuring device is construed in addition to measure the distance, which restores the welding element-holder towards the resting position. The distance-measuring device is formed in addition to measure the distance on digital, analogous or discrete basis. The detection- and the signal elements are formed in addition to record a movement of the welding element-holder relative to the drafted-element. The block- and the release element are formed in such a way that the detection- and signal elements are connected that it blocks the release of the welding process. The movement is recorded with the detection- element and signal elements, which lie outside the movement-target range, which comprises a standstill. The welding element-holder has no adjustment device for the adaption of different lengths of the welding elements. The drafted-element is formed in such a way that the welding element-holder is carried in an orientation unique for the welding process during drafting of the drafted-elements on a flat surface area of the workpiece. The position-target range is selected in such a way that the block- and the release elements block the release of the welding process. The position is recorded with the detection- and the signal elements in such a way that the welding element-holder is contacted after the drafting of the drafted-element on the plan surfaces area of the workpiece. The block and release elements are formed in addition to block or to release the release of the welding process in dependence of stud welding-parameters such as block contact detection and/or state of charge. An independent claim is included for a method for connecting welding-elements.
