Wire Arc Additive Manufacturing: Review on Recent Findings and Challenges in Industrial Applications and Materials Characterization (2021, methodology): “[71] developed a seconddegree regression model in which the bead geometry is described as a function of wire and torch speeds and the bead’s geometry is assumed to resemble a parabola, as shown in Figure 26.”
Wire-feed additive manufacturing of metal components: technologies, developments and future interests (2015, methodology): “For the GMAW-based WAAM process, due to the inherent characteristics of the process, the weld bead geometry within a weld pass is not uniform, particularly at the start and end portions.”
A multi-bead overlapping model for robotic wire and arc additive manufacturing (WAAM) (2015, background): “However, it has been observed through experimentation that it is impossible to achieve the ideally flat overlapped surface [22, 25].”
Bead modelling and implementation of adaptive MAT path in wire and arc additive manufacturing (2016, background): “Some preliminary investigations on multi-bead overlapping models have been made in recent years [22, 23].”
Modeling of bead section profile and overlapping beads with experimental validation for robotic GMAW-based rapid manufacturing (2013, methodology): “[18] assumed a symmetric parabola profile of the weld bead and fitted the boundary points by the parabola function with experimental validation.”
