摘要

The present study was aimed at studying the effect of type and composition of flux, welding current, arc voltage, and travel speed on depth of penetration, bead height and bead width (bead geometry responses) and to optimize the process considering multi-response criteria in a submerged arc welding process. Using the grey relational analysis technique three responses were combined into a single grey relational grade and was analyzed using Analysis of Variance. Since the three responses had conflicting requirements, optimization of the complicated multiple performance characteristics was greatly simplified through this approach. The emperical relationship between the multi-response grey relational grade and the input parameters was developed using regression analysis which was used to predict the value of the grey relational grade using the optimal parameter levels.
