Abstract—Submerged Arc Welding (SAW) is a common arc welding process and the basic characteristics
of this process are high deposition rate, ability to weld thick sections with ease and longer weld
runs because of the same reason it is used to join thick and heavy sections. The stress carrying
capacity of a weld determined by weld bead geometry. The models were developed in terms of
Arc Voltage, Arc Current, Travel Speed, nozzle to Plate distance obtained experimentally. The
Experimental data has been used to develop the models with the aid of regression analysis. The
effects of cutting variables (Arc Voltage, Arc Current, Travel Speed, nozzle to Plate distance) on
Bead Height, Bead Width, Bead Penetration have been investigated by Central composite Design
Index Terms—Submerged Arc Welding (SAW), Central composite design, Arc current, Travel
distance, Arc voltage, Weld bead geometry
