Modeling of Plasma Arc Welding of Inconel 617 Super Alloy Plates using RSM

Abstract

In the present work, an attempt is given to study the outcomes of input process parameters, namely weld current, weld speed and plasma gas flow rate on the bead geometry, that is bead width (BW) and bead height (BH) of Plasma Arc Welded Inconel 617 plates. In the present study, Bead on Plate (BoP) welding was done on 2 mm thick plates with the help of experiments designed using central composite design of experiments (CCD). The non-linear regression equations developed during this study were validated through experimental test cases. Further, it was depicted that the developed regression models were found to forecast the bead geometry with a reasonably good accuracy. � Published under licence by IOP Publishing Ltd.
