Development of Mathematical Models to Predict Clad Bead Geometry Deposited by GMAW In Stainless Steel Cladding

Weld Cladding is a process of depositing a thick layer of corrosion resistance material over carbon steel plate. The main problem faced in stainless steel cladding is the selection of optimum process parameters for achieving the required clad bead geometry. This paper highlights an experimental study carried out to develop mathematical models to predict clad bead geometry in Gas Metal Arc Welding (GMAW) process used in austenitic stainless steel cladding of low carbon structural steel plates. The experiments were conducted based on four-factor five level central composite rotatable design with full replications technique. The mathematical models was developed using multiple regression method.
