The aim of the present work was to study the effect of welding current, arc voltage, and speed on Nickel element transfer and to optimize the process following suitable Taguchi experimental design. Beads on plate weld were deposited on SS-316 at different welding parameter combinations. Welding volatge and speed were found to be the most significant factors leading to changes in Nickel element transfer. The results revealed that welding voltage has an appreciable influence on weld composition of nickel element. Data investigated in this paper can be used to specify welding variables for desired nickel composition.
