Abstract
The device comprises a welding unit with a tube (), a laser radiation unit () radiating in direction of the tube axis (), and a mandrel () which is connected to the tube () via a holding unit which is formed, e.g., by two spacer elements () and which is coaxially arranged relative to and in the tube (). The tube () and the circumferential surface of the mandrel () are reflective of the laser radiation of the laser radiation unit () such that through multiple reflections between the tube () and the mandrel () the laser radiation is deflected toward the beam output-side tube end () and is shaped annularly.
