Process Parametric Optimization of Submerged Arc Welding by Using Utility Based Taguchi Concept

Abstract:

Achieving optimal weld parameters with desired quality features is very difficult because these quality features are highly correlated. There are several control parameters which directly or indirectly affect the response parameters. In the present study, an attempt has been made to search an optimal parametric combination, capable of producing desired high quality joint in submerged arc weldment by Taguchi method coupled with Utility theory. In the present investigation three process variables viz. Wire feed rate (W_f), stick out (S_o) and traverse speed (T_r) have been considered and the response parameters are hardness, tensile strength (T_s), toughness (IS).
