Abstract Nowadays, there is a great manufacturing trend in producing higher quality net-shape components of challenging geometries. One of the major challenges faced by additive manufacturing (AM) is the residual stresses generated during AM part fabrication often leading to unacceptable distortions and degradation of mechanical properties. Therefore, gaining insight into residual strain/stress distribution is essential for ensuring acceptable quality and performance of high-tech AM parts. This research is aimed at comparing microstructure and residual stress built-up in Ti–6Al–4V AM components produced by Wire + Arc Additive Manufacturing (WAAM) and by laser cladding process (CLAD).

A review of wire arc additive manufacturing and advances in wire arc additive manufacturing of aluminium (2018, background): “The typical problem of formation of coarse columnar centimetre-scale β grains in a build direction (refer Figure 13), specifically associated with the Ti–6Al–4V alloy in the directed energy deposition format, was addressed by many researchers [15,16,48].”
Finite Element Modelling of Wire-arc-additive-manufacturing Process (2016, background): “Despite WAAM advantages, components manufactured with such technology are prone to residual stresses and distortions issues [3] affecting the subsequent machining operations [4].”
Metal additive manufacturing in the commercial aviation industry: A review (2019, background): “Due to the high heat generated by the arc, components manufactured by WAAM are subject to distortions and residual stress [56, 84, 85].”
The barriers to the progression of additive manufacture: perspectives from UK industry (2018, background): “, 2016), to date research literature remains more focused on fundamental processing dependant parameters (Dinda et al., 2009; Ding et al., 2015a; Szost et al., 2016; Wang et al., 2015).”
Control of residual stress and distortion in aluminium wire + arc additive manufacture with rolling (2018, background): “In all other measurements of WAAM samples [12], [16], [33], [48], [49] the stresses in the transverse and normal directions were relatively small in thin walls – hence a plane stress condition can be assumed.”
