Abstract
A method for resistance welding for welding two workpieces to one another using spot-welding tools. In the method, two electrodes of the spot welding tool are pressed against each other, and the electrodes are powered with energy. The workpieces are interposed and contact of the workpiece with the spot-welding tool is detected with a pressure element movably arranged on at least one of the electrodes and projecting beyond the electrode. The pressure element is then displaced relative to the electrode until the electrode contacts the workpiece.
