Influence of process parameters in Wire and Arc Additive Manufacturing (WAAM) process / Nor Ana Rosli...[et al.]

Wire and arc additive manufacturing (WAAM) has developed a wide range of
processes and applications. This technology is a new approach to modern
manufacturing and is gaining interest from the research community due to its
ability to create affordable, large-scale components. Nevertheless, WAAM
may affected by porosity, humping and undercut. These issues need to be
addressed in a specific way to achieve desired quality that is comparable to
the traditional processing technique. This article examines various weld travel
speeds, where defects start appearing. The effects of travel speed and wire feed
speed (WFS) were also discussed. It was found that, travel speed and WFS had
a major influence on deposition width and height and a stable deposited layer
was produced between heat input values of 0.2620 kJ/mm and 0.32756 kJ/mm.
