Definitions

  • the welding unit has a tube with a tube axis, a beam inlet-side tube end and a jet outlet-side tube end.
  • the laser beam unit is arranged with a radiation direction in the direction of the tube axis.
  • An inner circumferential surface of the tube is reflective for laser radiation emitted by the laser beam unit.
  • FIG. 1 b-1 g schematic diagrams for different cross-sections of the tube and the
  • the first mandrel part 4.1 here has the shape of a straight cone or a straight pyramid with a center angle ⁇ of less than 90 °.
  • the tip of the cone or the pyramid is directed toward the laser beam unit 1.
  • the first mandrel part 4.1 has exclusively the task of reflecting incident laser radiation onto the pipe 3 in such a way that it impinges there at an angle from which it is reflected further towards the pipe outlet end 3.2.
