Definitions
- the invention relates to a welding method in which the welding beam is moved in an oscillating manner.
- the object is achieved by a method according to claim 1.
- the figure shows schematically the arrangement of a build-up welding with a laser and a powder feed.
- the solidification front changes constantly, so that a oscillating solidification is realized.
- the grain growth is interrupted during the solidification of the melt and the structure solidifies one-grain.
- the fine graininess of the microstructure distributes the remaining residual welding stresses to the grain boundaries so that cracks in the weld seam or in the weld bead or between them are avoided.
- the welding process can be a remelting or an order welding. There is one for both methods
- the figure shows a device 1 of a welding process, in particular a laser welding process.
- the method is not limited to laser welding, but also applies to electron welding and other welding processes such as plasma welding or other additive manufacturing processes.
- a substrate 4 which is a nickel- or cobalt-based superalloy with high ⁇ ⁇ content in turbine blades and therefore generally a hard-to-weld alloy, material is applied.
- a weld bead 6 as part of the build-up weld has already been produced.
- a molten bath 7 is present.
- a powder nozzle as an exemplary material supply 10
- the powder 8 is melted.
- This laser radiation is in particular pulsed and the material 8 is supplied in the form of powder, but can also be supplied as a wire.
- the laser radiation or the energy supply 13 can be moved back and forth along the direction 16 vertical to the surface 5 of the substrate 4, so that a variation of the laser beam diameter is produced on the surface of the melt path 7.
- the deflection is preferably between 1mm and 2mm.
- an oscillating movement can be performed.
- the deflection of the oscillating motion is preferably between 1mm and 2mm.
- the surface to be welded has a length greater than or equal to 4 mm in at least one direction, i.
- a plurality of weld beads are produced or applied next to each other, which may also overlap.
- the vertical 16 or horizontal 19 movement can be used individually or combined with one another, both during remelting or build-up welding, and is superimposed on the forward movement of energy supply 13 with respect to substrate 4.
- plan view of the substrate 4 in the direction 16 with oscillating movement in the direction 19 thus results in a zigzag movement, a meandering or a sinusoidal movement.
