Intelligent process model for bead geometry prediction in WAAM

Materials Today: Proceedings, 2018
Abstract Wire and arc additive manufacturing (WAAM) is a predominant technique for metal based additive manufacturing process. In this process, generation of layers by depositing beads puts high emphasis on single bead geometry. This paper focuses controlling the bead geometry by suitable selection of welding process parameters.

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 ...
