Paragraph starter

The Wire-Arc Additive Manufacturing (WAAM) of Ni1Cu weathering steel, as demonstrated by Zhang et al. (2021), yields components with excellent mechanical properties, including high tensile strength (approx. 510-517 MPa) and significant impact resistance (130-147 J at -20 °C), alongside minimal defects. This suggests WAAM is a viable production method for creating robust, corrosion-resistant parts from this material.
