ICTM Aachen – International Center for Turbomachinery ManufacturingRepair with EHLA with optimized path planning for near net shape deposition
How can EHLA3D be utilized to precisely repair turbomachinery parts?
Challenge and Motivation
- Growing demand for resource-saving repair processes in turbomachinery applications
- EHLA enables a contour-accurate build-up with a smaller heat-affected zone and less need for rework
- EHLA processes a high diversity of turbomachinery materials, incl. superalloys like IN718 /IN738
Objective
- Gaining process know-how for tip repair applications
- Development of automated EHLA3D process chain for repairs (i.e. turbine blade) using adaptive path planning
