Optimization Process Parameter For Friction Welding Of Incoloy 800h Using Taguchi-Desirability Approach
Optimization of welding parameters on friction welding of Incoloy 800 H rod experiments were carried out by
Taguchi based Desirability Function Analysis (DFA). The welding parameters such as heating pressure (HP), upsetting
pressure (UP), heating time (HT) and upsetting time (UT) and its responses such as Tensile strength (TS) and burn off length
(BoL) were chosen for this work. The L12 orthogonal array designs of experiment were involved for conducting
experiments. The significance of quality of welding process was found by analysis of variance (ANOVA). The experimental
results indicate that the upsetting time and the heating pressure were recognized to make the most significant contribution to
the overall performance.
