Abstract
Austenitic stainless steel plates are welded using TIG-MIG hybrid welding process in butt weld joint and 1G position. The aim of present work is to investigate welded joint for ultimate tensile strength (UTS), ferrite content (FN) and solidification mode. Face cantered central composite design (FCCCD) of design of experiments (DoE) is used and control parameters (welding voltage (Wv), welding current (Wi) and welding speed (Ws)) are varied at three different levels to study nonlinear relationship between control parameters and desirables namely, ultimate tensile strength (UTS), ferrite content (FN) and solidification mode. Ferrite number (FN) is measured by feritoscope, and solidification mode and microstructure are studied by ratio of CrEq to NiEq (CrEq/NiEq) and FN. The results of CrEq/NiEq are correlated with actual micrographs for microstructural characterization.
