Abstract (en)
[origin: WO2017144048A1] The device contains a welding unit comprising a tube (3), a laser radiation unit (1) that emits laser radiation towards the tube axis (3.0) and a mandrel (4) that is arranged in the tube (3) coaxially with the latter and that is connected to the tube (3) by means of a retaining unit, for example formed by two spacer elements (5.1). The tube (3) and the circumferential surface of the mandrel (4) reflect the laser radiation of the laser radiation unit (1), such that the laser radiation is deflected towards the tube end (3.2) on the beam-exit-side and becomes toroidal, by multi-reflection between the tube (3) and the mandrel (4).
