Abstract:Wire-arc additive manufacturing technology has been widely recognized as a suitable method for fabricating large-size, complex, and high-strength aluminum alloy components. Two components were obtained by adopting a self-made low Cu 7A48 wire under the deposition parameters (a voltage of 18 V, a current of 85 A, a welding speed of 9 mm/s, and an argon flow rate of 23 L/min). One was the wire-arc additive manufacturing component of Al–Zn–Mg–Cu alloy, and the other was obtained via WAAM + micro forging hybrid pr… Show more
