Abstract Scope |
This paper evaluates the geometric and property repeatability of components printed by robotic wire arc additive manufacturing (WAAM). The WAAM system includes a KUKA KR 50 R2500 robot with a Fronius TPS 4000 welder. Gas metal arc welding (GMAW) is used for layer-by-layer deposition of ER4943-aluminum wire. A single geometry is printed five times using the same part plan, weld settings, and wire. The repeatability of the geometry and mechanical properties are then evaluated. For geometry, each component is measured using structured light scanning, 3D models are generated, and the deviations between each print are determined. For mechanical properties, tensile specimens are extracted using the ASTM E8 subsize tensile specimen standard. Tensile testing is then performed to determine the tensile strength, yield strength, and elongation. Experimental results are provided, and comparisons are drawn. |
