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).

Abstract

La refusion lors du soudage par apport de matière par l'intermédiaire d'une refusion de couches (7, 7', 7") soudées par apport de matière permet de régler une microstructure (10') aux grains agrandis souhaitée, qui permette d'obtenir des propriétés à haute température améliorés.
