Abstract

In this study, the parameters of PCGTAW process were optimized for the corrosion protection of SDSS weld pipes by Taguchi method. Analysis of variance is performed on the measured data and signal to noise ratios. The optimum conditions were found by this method. Under optimum conditions, pitting potential was predicted as 1.08 VSCE that was very close to the observed value of 1.06 VSCE. Among the four factors and three levels tested, it was concluded that the pulse current had the most significant effect on the pitting potential and the background current had the next most significant effect. The effect of pulse frequency and % on time are less important when compared to the other factors.
