• WAAM, Wire Arc Additive Manufacturing technology.• A high deposition rate additive manufacturing process, using arc welding and wirefeed systems.
Wire is melted using an arc welding process to create a bead.
Beads are overlapped to create layers.
The piece is created layer by layer.
Additive manufacturing versus casting/forging + machining • Lower raw material consumption. • Lower energy consumption.• Shorter lead time.
WAAM versus other additive technologies• Higher deposition rates.• Possibility to manufacture more large-scale parts and preforms.
