Definitions
- the invention relates to a method for producing a component according to the preamble of claim 1.
- Such a method is known for example from EP 868 253 B1.
- a filler is firmly connected to the component within a groove.
- the connection of the filler body with the component in the groove is not sufficient enough, since the solder or the connection layer between the filler body and the component is not uniform or incomplete.
- Figure 5 is a view of a component that is manufactured by means of the method according to the invention.
- Figure 6 shows a component after completion with the inventive method.
- Figure 1 shows a component 1 in a first process step.
- the component 1 has a groove 4, for example.
- Component 1 is, for example, a gas turbine component, such as a turbine blade.
- the turbine blade shows cracks after use that need to be repaired.
- the groove 4 is produced as in FIG. 1 or a corresponding groove 4 is present.
- FIG. 2 shows component 1 in a further process step of the method according to the invention.
- a filler 7 is to be firmly connected to the component 1 on a surface 8 of the component 1 or in a groove 7 (FIG. 2).
- a distance d of the packing 7 to the bottom 5 in the groove 4 can be zero or greater than zero.
- FIG. 3 shows component 1 in a further method step of the method according to the invention.
- a holder 13 is used which connects the filler 4 to the component 1 at least temporarily during a fastening process.
- the bracket 13 has at least one first bracket point 22 on the surface 8 of the component 1 and at least one second bracket point 25 on the filler 7.
- the spacers 10 are removed, for example, after the holder 13 has been applied, but can also remain in the gap 6.
- the holder 13 has an M shape.
- a first end of the M-shape of the holder 13 represents the first mounting point 22 on the component 1.
- the second end of the M-shape of the holder 13 represents a third fastening point 28 on the component 1.
- In the middle of the M-shape is the bracket 13 attached to the mounting point 25 with the filler 7.
- the M-shape of the holder 13 creates an open cavity 19 under the M-legs of the M-shape. As a result, the gap 6 is also freely accessible under the holder 13.
- solder material 16 for example in the form of solder paste or solder powder, is applied.
- soldering material 16 is melted and penetrates into the gap 6 and fills it completely.
- a hollow volume between the filler 7 and the base 5 can also be filled with the solder material if there is a non-zero distance d between the filler 7 and the base 5.
- FIG. 5 shows a top view of a component 1 according to FIG. 3.
- the top view shows that two brackets 13 are used to hold the filler body 7 in the groove 4. However, only one or more than two brackets 13 can also be used.
- FIG. 6 shows a component 1 which has been produced using the method according to the invention.
- connection layer 16 or solder layer 16 has been created between the filler body 7 and the component 1 in the previously existing gap 6. A firm connection between the filler body 7 and the component 1 is thus produced. Excess solder material on the surface 8 and the at least one holder 13 are removed in a last method step, for example by grinding.
- the filler 7 is welded in the groove 4, depending on the silent method, only a partial connection between the filler 7 and the component 1 can be made at the points generated where the bracket 13 is not present. In this case, a connection, weld seam, is created at the accessible points. As a result, a sufficiently firm connection between the filling body 7 and the component 1 is initially produced. Then the at least one holder 13 can be removed and the freely accessible area of the gap 6, which was previously covered under the holder 13, can also be provided with a connection layer 16 by means of welding or other connection methods. The filler 7 is then completely connected to the component.
- Such a method can be used when repairing cracks.
