Original Article


The mechanical and corrosion resistant properties of cladded components depend on the clad bead geometries, which in turn are controlled by the process parameters. Therefore it is essential to study the effect of process parameters on the bead geometry to enable effective control of these parameters. The above objective can easily be achieved by developing equations to predict the weld bead dimensions in terms of process parameters. Experiments were conducted to develop models, using a three factor, five level factorial design for 317L flux cored stainless steel wire with IS:2062 structural steel as base plate. The models so developed were checked for their adequacy. Confirmation experiments were also conducted and the results show that the models developed can predict the bead geometries and dilution with reasonable accuracy. It was observed from the investigation that the interactive effect of the process parameters on the bead geometry is significant and cannot be neglected.
