Aluminum alloy, due to its lightweight, is widely used in automobile, shipbuilding and aerospace applications. Wire arc Additive Manufacturing (WAAM) has gained significant attention in recent years due to its higher production rates for large and complex customized parts. This experimental work investigates the mechanical properties of Aluminum 5356 alloy manufactured wall using robotic-controlled gas metal arc welding (GMAW)-based WAAM. The deposition of layers was carried out in automatic mode using proper path planning. The tensile tests and fractography were conducted to investigate the mechanical properties in both longitudinal and transverse directions of the deposition. It was found that ultimate tensile strength and elongation along the transverse direction achieved 13.8% and 73.8% higher values than in longitudinal directions, respectively. Some defects are observed due to the accumulation of heat and some inevitable conditions during the automatic deposition process on the top advancing layers.
