[ABSTRACT ]

The additive manufacturing process can be carried out with a welding-based process. The welding process that can be used to manufacture metal products or components with arc welding technology is Tungsten Inert Gas (TIG) welding. This study presents the effect of current and polarity on multilayer WAAM-based TIG welding with ER 5356 and ER 1100 filler materials on SS316 base plates. The influence of current and polarity in TIG welding is evident from the weld bead's geometry, appearance, and quality. The experimental results of the welding bead on DC polarity are more consistent than those on AC polarity.
