Synopsis

In this research work wire arc additive manufactured (WAAM) components have been prepared with 1.2 mm diameter 4043 filler wire on 8mm thick pure aluminum substrate by employing Gas Tungsten arc welding (GTAW) as an arc source. This paper explores the influence of macrostructure, microstructure and mechanical properties of WAAM deposit samples by applying different process parameters. Double and triple layered deposits are built by keeping deposition mode, deposit speed, gas flow rate and deposit current constant. The effect of time interval between the deposits, use of copper core and re-melting of the deposit on solidified structure are investigated.
