Porosity reduction in metal with hybrid wire and arc additive manufacturing technology (WAAM)

CIS Iron and Steel Review
Among different additive manufacturing (AM) methods, wire and arc additive manufacturing (WAAM) is the most suitable for manufacture of large-size metal components due to high deposition rates, which are rather higher than that for a powder laser and ...
