Definitions
- the invention relates to a construction strategy in order ⁇ a weld crown bottom of a turbine blade and the turbine blade thus prepared with a squealer on the crown ground.
- the tips of a turbine blade underlie ⁇ gene stronger wear and are repaired for reuse, which again material must be applied to the original geometry, the so-called squealer edge, a circumferential wall along the outer contour of the
- Airfoil applied and should also be inexpensive to manufacture.
- the corresponding traverse strategy of the welding head also plays a role.
- Figure 1 is a plan is applied to a surface of a turbine acting ⁇ fel, on the material
- FIG. 3 shows a procedure of the building strategy
- Figure 4 shows a turbine blade
- Figure 5 is a list of superalloys.

- an outer circumferential weld 10 is placed along the contour 7, before the first step
- Welding webs are applied for welding layers.
- circumferential wall 13 hardfaced is set preferential ⁇ well as an inner circumferential weld 11 along a path to be generated inner contour 8, before the first welding lines between the contours 7 and 8 are plotted for welding positions.
- Figure 2 is a cross section of a desired geometry of a crown bottom 4 with a circumferential wall 13, in particular a tip squealer of a turbine blade, and shown a hollow space ⁇ . 6
- the wall 13 is at least two welding track widths wide. In the middle of the surface 4, 415, an upwardly open cavity 6 with the inner surface 5 forms.
- FIG. 3 shows first steps for the large-area construction of material, in particular for a circumferential wall 13.

- the second welding layer covers the first welding position.
- the lines 33 33 ⁇ ⁇ , ... represent only the relative movement between the blade tip and the welding head, ie when the inner surface 5 is generated, no material is applied there by stopping the supply of material in the region.
- the second welding location preferably starting at one end 40 of the face 4, 415 and then by following directly aneinan ⁇ the adjacent or preferably overlapping sheeting coated.
- the welding tracks 33 (33 ', 33 ",...) are laid parallel to a transverse line 23.
- the transverse line 23 is preferably aligned transversely to the longitudinal direction 20 of the surface 4, 415.
- the weld beads 33 ', 33 "preferably start at one end, e.g. B. 40 of the surface 4, 415 and run straight. If the welding path leaves the outer contour 7, the application process is moved to the next welding path displaced by a certain distance. In the areas in which the cavity 6 is formed, no material is applied, so that the transverse line 23 or Paralle ⁇ len to only the course of the relative movement between the substrate 120 and welding head (not shown) represent. In the first welding position, the surface 4, 415, with
- Material is to be coated, completely generated with parallel ver ⁇ running welding paths 33.
- the welding paths are laid, preferably continuously from one side, here 40, 412 to the other side, here 409 (FIG. 4).
- a second welding layer of welding paths is produced, which are laid parallel to a longitudinal line 20 (26, 29), wherein the longitudinal line 20 transverse to the transverse line 23, in particular at an angle 70 ° to 110 °, in particular 80 ° extends to 110 ° to the transverse line 23.
- the longitudinal centerline 20 extends perpendicular to the transverse line ⁇ 23rd
- the second welding layer covers the first welding position.
- the lines 26, 29, ... represent only the relative movement between the blade tip and the welding head, ie when the inner surface 5 is created, no material is applied there by stopping the supply of material in the region.
