Abstract Control of the melt pool size is necessary to achieve more homogenous material properties in wire arc additive manufacturing (WAAM). The can be measured by camera imaging or temperature field measurement. paper aims investigate feasibility using a high dynamic range two-colored pyrometric (Pyrocam) for measurement gas metal welding–based WAAM process. A set band-pass filters identified spectroscopy analysis reduce optical emission while remains visible. fusion line images, an...
Abstract Wire arc additive manufacturing (WAAM) of titanium parts shows promising potential for aerospace application due to its high deposition rates allowing a fast and economical production large components. The cost savings are high, especially expensive alloys like Ti-6Al-4V. However, oxygen affinity Ti-6Al-4V at elevated temperatures an excellent shielding gas coverage seems necessary prevent embrittlement the material during welding process. Regarding future development local set-ups...
Wire arc additive manufacturing (WAAM) of titanium parts shows promising potential for aerospace application due to its high deposition rates allowing a fast and economical production large integral parts. However, the demands industry an extensive qualification procedure is necessary enable as ready fly. Nowadays, manufactured time-consuming process, so advantages in cannot be fully utilized. For this reason, complete process WAAM would reduce costs drastically contrast qualifying...
