Structural integrity of the WAAM-substrate interface

Wire + Arc Additive Manufacturing (WAAM) is a form of directed energy deposition for additive manufacturing of metals. An electric arc is used to melt metal feedstock wire, allowing material deposition in a layer-by-layer fashion. In addition to newly manufacturing workpieces, WAAM could also be applied for the remanufacturing of damaged or worn ...
