Abstract Scope |
While metal AM research often focuses on high-cost materials, lower-cost alloys such as low carbon steel are used at higher volumes in the casting industry. Welding is a standard process step in casting production, but robotic automation has been limited due to this industry’s low-volume and high-mix. However, advances in flexible automation show their potential. This research presents the application of WAAM using a 6-axis robot arm with low carbon steel castings. Process parameters, including travel speed, cooling time, and step over distance, are evaluated for their effect on the resulting geometry. Demonstration parts assess the ability to produce objects with varying geometries without defects. A method is discussed for depositing material on non-planar surfaces, such as the filling of a concave feature. These findings broaden the scope of applications in which wire arc additive manufacturing can be applied in industrial applications and develops parameters for depositing within non-planar cavities. |
