Turbo engine components repair methodology by Laser Material deposition

Abstract

 Additive Manufacturing (AM) is an on growing technology in 
the last decade. Aeronautical industry, among others, is getting 
involved in this new trend for manufacturing and repairing 
processes. More concrete inside AM techniques, Laser Metal 
Deposition (LMD) is a versatile process with the capability of any 
repairing task, though the use of this technology is considered 
a multidisciplinary process that requires knowledge of several 
aspects: 3D digitalization, CAD/CAM programming, and the 
laser cladding parameters and control. Considering these many 
challenges, this work states a global vision through all process 
stages in order to implement LMD repairing technology in several 
industries. 
Additionally, trials were performed related to different process 
stages with significant results serving as initial reference for 
turbomachinery rotary components repairs. Finally, advantages 
and drawbacks of LMD process, as well as industrial pioneering 
companies at this sector
