Abstract	Double Pulsed GMAW (DP-GMAW) has been recognized as a new and efficient technique for quality welding. The double-pulsed GMAW (DP-GMAW) technique is a variation of the pulsed GMAW technique, in which the pulsing current aimed to metal transfer control is overlapped by a thermal pulsation, which in turn means pool control. The weld bead plays an important role in determining the mechanical properties of the weld. Its geometric parameters, viz., width, reinforcement height, and penetration, are decided according to the welding process parameters. Therefore, to produce good weld bead geometry, it is important to set the proper welding process parameters. In this study, the regression modeling is used in order to establish the relationships between input and output parameters for DP-GMAW. To gather the required data for modeling, actual tests were carried out based on the proposed Taguchi experimental matrix design. The purpose of this study is to find a regression model of the welding process parameters in order to obtain the desired geometry. The adequacies of the models are then evaluated using analysis of variance (ANOVA) technique. The model developed was checked for their adequacy. Results of confirmation experiments showed that the model can predict the bead geometry with reasonable accuracy.
