Abstract: There are several bead geometry parameters which indicate quality of submerged arc weldment. These includes, bead height, penetration depth, bead width, percentage dilution etc. Achieving an optimal weld, with desired quality features, is really a challenging job. Because, these quality features are highly correlated and are expected to be influenced directly or indirectly by the direct effect of process parameters or their interactive effects (i.e. on process environment). However, the extents of significant influence of the process parameters are different for different responses. Therefore, SAW is a multi-factor, multi-objective metal fabrication process. It is desired that, an optimal weld should confirm lesser bead height and width, to reduce excess weld metal consumption; deeper penetration and higher parentage of dilution, in order to increase joint strength. Therefore, to solve such a multi-objective optimization problem, it is felt necessary to identify the optimal para...
