The aim of this article is to optimize the process parameters for friction welding of Incoloy 800 H rod by Taguchi based Grey relational analysis (GRA). The objective variables chosen were Tensile strength (TS) and burn off length (BoL) which is dependent upon heating pressure (HP), upsetting pressure (UP), heating time (HT) and upsetting time (UT). The experiments were carried out using L12 orthogonal array. Each experiment has been performed using different process parameters. The importance of process parameters on quality of welding process has been evaluated by analysis of variance (ANOVA). This work has also showed the application feasibility of the Grey relation analysis in combination with Taguchi technique for continuous improvement in welding quality.
