Abstract
The present work deals with optimization of Shielded Metal Arc Welding process on Duplex Stainless steel (DSS 2205). Welding is an important technology in Duplex Stainless steel alloy application where the quality control is too important. Taguchi L9 orthogonal array method was employed to optimize the welding process parameters of DSS 2205 weld for minimizing the angular distortion after weld and improving equal percentage of ferrite and austenite content in weld metal. Four variable welding parameters and their three levels were selected and design of experiment (DOE) was implemented as per Taguchi L9 array. Descriptions of angle of deviation measurement techniques and data analysis are presented. The present investigation is to find out the best influence of welding current, Welding Speed, Welding Position and filler material on angular distortion.
