Abstract This article explores the reason behind higher deposition rate in Mg-containing aluminum alloys gas metal arc welding (GMAW). Experiments performed on ER1100 (Mg-free alloy) and ER5183 (high Mg alloys) measured current, wire feed speed, droplet temperature. A non-linear analysis of Joule heating at electrode extension an power needed to heat consumable temperature were performed. Analy...

The experiments of wire arc additive manufacturing (WAAM) with general pulsed gas metal welding (GMAW) machine were performed to optimize process parameters. As optimized conditions, 140A current, 34 V voltage, 40 cm/min speed, and 15 mm contact tip work distance (CTWD), selected. Welding current voltage affected heat input. Lower deposition, short circuit mode, spatters obtained by insufficien...

Gas metal arc welding (GMAW) is a highly efficient and fast process for fabricating high quality weld. High quality welds are fabricated by proper selection of consumable includes gas and filler metals. The optimum flow rate of gas will ensure the proper quality of weld. In this project, a fluid flow behavior of different flow rate is modeled and the change quality will be studied. KeywordsHydr...
