Manufacture and repair of aero engine components using laser technology

This paper gives an overview about developed and industrially implemented manufacture and repair processes such as Laser Metal Deposition (LMD) and Selective Laser Melting (SLM) for additive manufacture and repair of parts and Laser Drilling (LD) for manufacture of instrumentation holes. Characteristic features of the processes are described and discussed. Components under investigation are e.g. High Pressure Compressor (HPC) BLISKs, High Pressure Turbine (HPT) Vanes and Blades, HPT Liners and Combustor Swirlers made of Titanium and Nickel base alloys such as Ti-6Al-4V, Ti-6246, In 718, Rene 80, Mar-M 002, Mar-M 247, and CMSX-4. The paper is completed by the presentation of installed machines at the customer's site.
