Effect of Saw Parameters on Chromium & Vanadium Elements Transfer in SS-202Download PDF
The aim of the present work was to study the effect of welding current, arc voltage, and weld speed on Chromium and Vanadium 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 Chromium Welding voltage and current were found to be the most significant factors leading to changes in chromium element transfer. During analysis of Vanadium Welding speed and current were found to be the most significant factors leading to changes in vanadium element transfer. The results revealed that welding voltage has an appreciable influence on weld composition of Chromium element and welding speed has an appreciable influence on weld composition of vanadium element. Data investigated in this paper can be used to specify welding variables for desired Chromium and Vanadium composition.
