Analysis of Favourable Process Conditions for the 2 Manufacturing of Thin-Wall Pieces of Mild Steel 3 Obtained by Wire and Arc Additive Manufacturing 4 (WAAM)

One of the challenges in additive manufacturing (AM) of metallic materials is to obtain workpieces free of defects with excellent physical, mechanical, and metallurgical properties. In wire and arc additive manufacturing (WAAM) the influences of process conditions on thermal history, microstructure...
