In the presents study, the optimization done for brazing process parameters for joining Ti-6Al-4V to itself and stainless steel using low temperature silver based alloy in the form of a foil type brazing filler metal in the vacuum furnace. The brazing joint clearance, brazing temperature and the brazing time are chosen to be the design parameters to have massive impact on the bonding potential of a brazed joint. Taguchi method is employed as a statistical method for designing of experiments with an effort for optimizing the brazing conditions in terms of shear strength. L9 (33) orthogonal array is design for conducting the experiments. The relative impact of the design parameters and also their interaction over the response are also discussed. The results obtained from the experiments showed that the brazing conditions found in this work by Taguchi technique could generate the brazed joints between Ti-6Al-4V to itself and stainless steel with maximal shear strength.
