WAAM boat sample finished with 200 deposition layers. We adopted RDT intermittent welding process, Megmeet Artsen Mate 400 welding machine and 1.2mm carbon steel wire for this WAAM test. RDT intermittent welding precisely controls heat input, reduces interlayer thermal stress and cumulative deformation, stabilizes contour and minimizes collapse & undercut defects, improving manufacturability for large carbon steel components. WAAM leverages proven welding power source with cost advantages for rapid fabrication of medium & large metal parts. This boat demo verifies stable performance of Mate 400 in layer-by-layer cladding, supporting WAAM adoption in marine, construction machinery and other industries.
