Cladding is a surface modification process in which a
specially designed alloy is surface welded in order to enhance corrosion
resistant properties. Common cladding techniques include Gas Tungsten Arc
Welding (GTAW), submerged arc welding (SAW) and gas metal arc welding (GMAW).
Because of high reliability, easiness in operation, high penetration good
surface finish and high productivity gas metal arc welding became a natural
choice for fabrication industries. This paper presents central composite
rotatable design with full replication techniques to predict four critical
dimensions of bead geometry. The second order regression method was developed
to study the correlations. The developed models have been checked for adequacy
and significance. The main and interaction effects of process variables and
bead geometry were presented in graphical form. Using fmincon function the
process parameters were optimized.
