Abstract
In the current scenario cladding process are used in many engineering industries to enhance the corrosion resistance surface and wear resistance of the base material in chloride environment. Cladding of stainless steel results in formation of ferrite number content on cladded surface, which deleterious the material properties. The present investigation address the effect of process parameters on ferrite number during austenitic stainless steel 317L cladding by Pulsed Metal inert gas (MIG) welding process. Ferrite number was measured by using Fisher’s ferrite scope. Response surface methodology (RSM) based central composite rotatable design were approached to predict and develop the mathematical model for process parameters such as welding current, welding speed and contact tip to work distance on ferrite number. From the analysis of variance technique it is found that the developed mathematical model was significant. The developed mathematical model is useful to control and determine the ferrite number content in austenitic stainless steel cladding. The direct and interaction effects of input process parameters are presented graphically.
