<p>The invention relates to a robot-compatible welding device (1) with a welding head (7) and a pressure-exerting device (11) with at least one pressure-exerting element (12) and with an infeed device (15), which has an actuating drive (18). The actuating drive (18) has two rolling membrane cylinders (19, 20), which are acted on from one side and have opposing directions of effect (28, 29), or one rolling membrane cylinder, which is acted on from two sides. The rolling membrane cylinders (19, 20) are controlled to a constant force.</p> |
