Repair process:

Surface preparation (grinding/sanding). Decontamination. FIller Application.

The automated LE repair consists of 5 steps:

No

Step

Description

Time necessary

1.

Laser scan

Scan the blade before the repair and generate a 3D model of the blade in 12 μm (micrometer) precision to assess the blade condition and adjust the tools.

15min

2.

Grinding and sanding

Remove the damaged/eroded layer to allow for application of a new layer of filler.

10-20min

3.

Decontamination

Clean up the blade and prepare it for filler application to provide maximal durability of the material applied later.

10-20min

4.

Filler application and profiling

Apply an exact amount of the filler material on the blade and profile it in a high-precision.

10-20min

5.

Laser scan

Scan the blade after the repair to validate the result and guarantee the highest quality.
