The aim of the present work was to study the effect of welding current, arc voltage, and weld speed on Manganese and element transfer and to optimize the process following suitable Taguchi experimental design. Beads on plate weld were deposited on SS-202 at different welding parameter combinations. During analysis of Manganese Welding voltage and current were found to be the most significant factors leading to changes in manganese element transfer. The results revealed that welding voltage has an appreciable influence on weld composition of Manganese element. Data investigated in this paper can be used to specify welding variables for desired manganese composition.
