Abstract: (677 Views)
Today, the wire arc additive manufacturing process is based on gas metal arc welding as one of the electric arc fusion processes, widely used in the industry due to its high efficiency. The correct selection of input parameters directly affects the welding quality, and by controlling those parameters, the amount of welding material can be reduced, its properties can be improved, and then the efficiency of the process can be increased. In this research, the production of a composite sample with a combined electrode by gas metal arc welding (GMAW) was investigated. At first, the welding speed, voltage, and wire speed were selected by studying and checking the effective parameters of the process in the wire and arc additive manufacturing (WAAM) by gas metal arc welding. Then, in order to evaluate the effects of effective welding parameters, three three-level factors were designed by the Taguchi method in Minitab software with an L9 array-related experiment. After performing the appearance review process, tensile and microhardness tests were performed. The tensile test results showed that the highest tensile strength is 294.327 MPa in the sample with a welding speed of 86 mm/min, voltage of 32 V, and wire feeding speed of 6 m/min. The microhardness test results showed that the highest value of microhardness was 463.1 Vickers for the sample produced with a welding speed of 86 mm/min, voltage of 27 V, and wire feeding speed of 5 m/min.
