Definitions

  • the invention relates to an adaptation of the power during the wobble of an order strategy during welding.
  • Welding processes are carried out on metallic components in order to apply missing material or to achieve three-dimensional structures.
  • Laser welding processes in particular powder application processes, in particular laser powder deposition welding processes, are currently frequently used. In these methods, but also in other methods in which powder or the material is supplied in any other way, a Wobbeistrategie is applied, in which the energy beam and substrate oscillate relative to each other.
  • FIGS. 1, 2 show the schematic procedure of the method.
  • a laser beam build-up welding with powdered filler material using a pendulum motion in the form of a sinusoidal or zigzag oscillation is performed.
  • an adjustment of the laser processing Leis ⁇ P to the reciprocal points 16 16 ⁇ ⁇ , in particular with a reduction of the laser power P in particular 90% of P m ax is performed.
  • Nickel-base superalloys avoid epitaxial growth of columnar grains over several layers, so that the risk of formation of critical hot cracks is increased. is reduced during the solidification and / or the subsequent heat treatment.
  • FIG. 1 shows the relative method of operation 13 (FIG. 2) of the energy beam, in particular of a laser beam
  • FIGS. 1 and 2 show the relative method of operation 13 (FIG. 2) of the energy beam, in particular of a laser beam
  • FIG. 2 shows the arrangement of material flow and energy beam 7 (FIG. 2) with respect to a substrate 4.
  • the energy beam in particular the laser beam, is allowed to oscillate.
  • the course of the oscillation ie the deflection or deflection and the simultaneous change of the power P is plotted against the time t in milliseconds.
  • the oscillation 13 has, as is usual with a sine curve, at least one sweeping point 16 16 ⁇ ⁇ , ....
  • the sine curve is only one example of a wave-shaped movement, such as a zigzag movement, which has sweeping points 16 16 ⁇ ⁇ .
  • the energy beam is laser beam 7 such a sweeping point 16 16 ⁇ ⁇ (max / min point)
  • the laser power was in advance in particular continuously reduced and there ⁇ by up again, that is in the range of the sweeping point 16 16 ⁇ ⁇ is the laser power L shut down in advance to a lower laser power and then again in particular continuously ramped up to the original previous value P ma x for a time t max .
  • t m i n and t max give half the oscillation period of the sinusoid and it is preferably t max ⁇ 0.3 t m i n ⁇
  • P max is preferably greatest when the sinusoidal curve or oscillation passes through the zero line 17.

Abstract

L'invention concerne une modification de la puissance lors d'une modulation. Lors de la modulation, la puissance laser (P) est temporairement diminuée dans la zone du point d'inversion (16`, 16``,...), ce qui permet d'obtenir de meilleurs résultats de soudage.
