Abstract Scope |
Wire arc additive manufacturing (WAAM) is commonly used for low volume production and repair of metal parts due to its reduced time and cost compared to casting. The selection of appropriate weld parameters is required to ensure fusion between beads, reduce porosity, and decrease defects. Additionally, path adjustments affect the heat distribution within each layer and the part dimensional accuracy. Gas metal arc welding (GMAW) tests were conducted with a KUKA KR 50 R2500 robot equipped with a Fronius welder to determine parameters for cold metal transfer (CMT) welding of 4943 aluminum. Using the CMT 1368 Adv (v1.2.0) synergic line, sufficient fusion between beads and weld quality was observed. Slicing programs were made in Rhinoceros7 and were used to modify the welding path so that dimensional inaccuracies from thermal gradients were reduced. WAAM of large aluminum components provides efficient production of complex parts for commercial and defense applications. |
