1.Laser Cladding (LMD)
Laser Cladding o Laser Material Deposition (LMD) Both, the substrate and filler material are melted with a laser. Generally, filler material is injected as a powder stream by a nozzle Wire feeders can be also applied. TECHNOLOGY REQUIRED EQUIPMENT Laser: Usually solid state or diode laser. Powder feeder: Lower mass rates than plasma spray systems. Nozzle: Powder injection into the melt-pool. Kinematics: Machine-tool or Robot to guide the nozzle. 5 axis interpolation ability highly recommended. MATERIALS Superalloys (Ni, Ti, ). Tool steels. Stainless steels. Ceramic materials. Structural steels. Aluminum alloys.

2. WAAM TECHNOLOGY
WAAM: Wire Arc Additive Manufacturing Based on arc welding The substrate and the filler materials are melted by the arc transfer between the electrode of the torch and the substrate material. The material is injected as a wire. There are different systems for generating the arc (TIG, MIG, PAW, CMT). Required equipment Conventional welding equipment: PAW, TiG, MIG, CMT Torch Wire feeder and positioner Kinematic: Machine-tool or robot Application High added value parts repairing Manufacturing of components or parts of components with high material waste Big size part manufacturing Hybrid manufacturing.
