Definitions
- the invention relates to a laser method in which a
- the invention simplifies the operational and procedural preheating during welding and the generation of larger temperature gradients. Show it:
- Laser beam regions 7, 4 has.
- an inner laser beam region 7 having a higher intensity or power, preferably from 200W to 300W, and a crack in the substrate 20
- the inner laser beam area 7 is, preferably
- an outer laser beam region 4 which has a larger cross-section, in particular a larger diameter and has a lower intensity or a lower power, so that the outer
- Laser beam area 4 the area in front of and behind the inner laser beam area 7 only preheated and reheated when the
- Laser beam 1 is moved over the substrate 20.
- Laser beam range 4 is at least 3.5mm, in particular at least 4mm, most preferably 4mm.
- the inner region 7 is preferably arranged concentrically in the outer region 4.
- Such a laser beam 1 can preferably be generated by a bifocal lens 10, in which a laser beam 13 with a single wavelength ⁇ through the bifocal lens 10 correspondingly in an inner 7 and outer 4
- Material can be supplied by the laser beam 1, in particular by the inner laser beam area 7,
- Laser beam 1 ⁇ consists according to Figure 2 in that an incoming laser beam 14 has two different wavelengths ⁇ , ⁇ 2 , which are different strongly refracted by a single lens 11 and so the different
- the temperature gradient is increased perpendicular to the substrate 20 and such a laser beam 1, 1 ⁇ can preferably be used during the
- monocrystalline remelting or build-up welding can be used.
- 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 powers of the laser beam regions 4, 7 to one another is at least 1.2, in particular at least 1.5.
- the area of the inner laser beam area 7 is the area of the inner laser beam area 7 .
- FIG. 3 shows an intensity distribution according to the invention.
- the inner laser beam region 7 is arranged concentrically within the outer laser beam region 4.
