Definitions
- the invention relates to the remelting of build-up welding layers.
- Service-demanding components such as gas turbine engines known for turbine blades, perform repair welds by applying material thereto.
- Figure 4 is a list of superalloys.
- FIG. 1 shows as a starting point a component 1 with a substrate 4 on which there is a build-up weld 8 made of a job-welded layer 7.
- the substrate 4 is metallic and, in the case of gas turbine components, preferably a nickel- or cobalt-based superalloy, in particular according to FIG. 4.
- the application weld 8 is present on a surface 13 of the substrate 4, preferably by laser deposition welding.
- the material of the build-up weld 8 may correspond or be similar to the material of the substrate 4.
- the surface 16 'of the build-up weld 8 is treated with a laser beam, so that within the welded layer 7 a remelting area 10 with a surface 16 "is formed.
- FIG. 2 shows a further exemplary embodiment of the invention, in which several application-welded layers 7 ',
- not all the job-welded layers 7 ', 7 ", 7"' are detected. This is particularly the case when the height of the supporting welded on ⁇ layers 7 ', 7'',7''' is smaller than that to be achieved remelting of Umschmelz Symposiums 10 '.
- the remelting region 10 ', 10 (FIG. 1, 2) or an application weld 7 V according to FIG. 3 can then represent the outermost surface 16 ", 16", 16 IV , onto which metal is then deposited in a known manner Protective layers (MCrAlX, PtAl, ...) and / or ceramic thermal barrier coatings (ZrO 2 - Y 2 O 3 ) be introduced ⁇ .
- This process is preferably suitable for polycrystalline solidified substrates 4 (FIGS. 1-3).
