Definitions

  • the invention relates to lasering, in which a laser beam is used which has two different laser beam ranges.
  • the temperature field should be designed so that thermal compressive stresses are generated in the trailing area.
  • the object is achieved by a method according to claim 1.
  • the figure shows schematically the invention.
  • an intensity distribution of a laser beam 1 according to the invention is shown.
  • An inner laser beam area 7 is not arranged concentrically to an outer laser beam area 4.
  • an inner laser beam area 7 which has a higher intensity or a higher power, in particular 30-1000 W / mm 2 , very particularly 100-300 W / mm 2 and can melt a crack or material for a Build-up welding can melt.
  • the inner beam portion 7 is preferably completeness dig, surrounded by an outer beam portion 4 which has a larger cross section, in particular a larger diameter and has a smaller intensity, or a ge ⁇ ringer laser power before so that the outer beam portion 4 to the area and behind the inner laser beam area 7 only preheated or reheated.
  • the diameter of the inner beam portion 7 1mm and that of the outer beam portion 4 is preferably be ⁇ carries 4mm.
  • the inner region 7 is not arranged concentrically in the outer laser beam region 4. As a result of this intensity distribution, the temperature gradient in the beam direction of the laser beam 1 is increased, and such a laser beam 1 can preferably be used in monocrystalline remelting or build-up welding.
  • An example of a substrate having a directionally solidified structure is PWA 1483SX, which gives a monocrystalline structure.
  • the ratio of the intensities or the power of the laser beam regions 4, 7 to one another is at least 1.5, in particular ⁇ at least 2.
  • the surface of the inner laser beam region 7 is preferably ⁇ a maximum of 25% of the outer laser beam area. 4
  • the inner laser beam region 7 is closer to the region to be remelted.
  • the inner laser beam region 7 may be arranged with its edge on the edge 9 of the outer laser beam region 4 (not shown) or have a distance from the edge of the outer laser ⁇ beam region 4.
