Compared to laser powder buildup welding, laser wire buildup welding bears significant advantages such as 100% material utilization, clean processes, high surface quality and a low chemical reactivity due to smaller specific surfaces. Thanks to the novel IWS COAXwire processing head, wires can now also be processed independent from direction with high geometric degrees of freedom.
Tensile strength was above the one specified for the wire and is consistent with hardness measured, ranging from 800 MPa to 1 GPa depending on the heat input. Deposition rates from 122.9 to 427.5 cm3/h were obtained. Keywords: additive manufacturing

2017/2/3· Wire arc additive manufacturing (WAAM) uses an electric arc as a heat source and wire—rather than powder—as feedstock. One of the advantages of WAAM technology is that it can be implemented using off-the-shelf welding equipment, which makes it an appealing option for job shops that don’t want to invest in an expensive powder bed system.
