Laser metal deposition manufacturing (LMD)

A 5 axis laser metal deposition manufacturing method developed by TWI for an EU-funded project which is demonstrating drastic time reduction in the manufacture of aero engine casings.

In LMD, a weld track is formed using metal powder as a filler material which is fed, through a coaxial nozzle, to a melt pool created by a focused high-power laser beam. By traversing both the nozzle and laser, a new material layer develops with precise accuracy and user-defined properties. The application of multi-layering techniques allows 3D structures to be created.
