Definitions
- the invention relates to a method for build-up welding in which the microstructure of the welded-on region is set in a targeted manner.
- the invention relates to laser beam deposition welding with a powdery filler material using a pendulum motion (wobble strategy).
- the Wöbbel strategy for laser cladding allows targeted control of nucleation and grain growth in the mushy zone, so that the growth of a colum- lic solidification front is suppressed or completely avoided.
- Experimental results show a nearly crack-free microstructure on the nickel-based superalloys IN738.
- the object is achieved by a method according to claim 1 and a component according to claim 6.
- FIG shows a component according to the invention.
- the figure and the description represent only embodiments of the invention.
- the advantage lies in improved material properties of the component compared to conventionally welded components.
- the figure shows a component 1 with a substrate 4 and a job-welded area 13 (material application).
- the component 1 had at least one crack or defect which was removed, so that for re-use of the component material must be reapplied or a new component is constructed hybrid.
- the substrate 4 of the component 1 is preferably a nickel- or cobalt-based superalloy.
- Material is applied to the surface 12 of the substrate 4 to be processed.
- the difference in thickness between the directly successive thick application layers 7 7 ⁇ ⁇ , ... and thin order layers 9 ⁇ , 9 ⁇ ⁇ , ... is at least 20% (relative).
- the sequence of thinner 9 ⁇ , 9 ⁇ ⁇ and thicker 7 7 ⁇ ⁇ on ⁇ tragslagen can be varied as desired, ie either first the thin 9 ⁇ or first the thick order layer 7 ⁇ .
- the thick order layers 7 ⁇ , 7 ⁇ ⁇ , ... may also be formed differently thick, but are always at least 20% thicker than the thickest order of the thin order ⁇ layers 9 ⁇ 9 ⁇ ⁇ ....
- the figure represents only an example of the invention, in which the sequence of thinner 9 ⁇ , 9 ⁇ ⁇ , ... and thicker 7 ⁇ , 7 ⁇ ⁇ , ... order layers is alternating.
- the material for the thick and thin order layers is preferably the same.
- the material composition of the thick 7 ⁇ , 7 ⁇ ⁇ and thin 9 ⁇ , 9 ⁇ ⁇ order layers can be varied, alternating or graded, these following examples are not limiting:
- Material 1 and material 2 differ at least by 20% in an alloying ingredient or at least one alloying element more or less. There may be at least 4, in particular at least 8, completely in ⁇ particular at least 12 order situations.
- the laser parameters are optionally adapted to a lower or higher powder mass flow:
