Abstract
The purpose of the present investigations is to study statistically controlled solution (from sensitization point of view) for 304 stainless steel (ss) joints using tungsten inert gas welding (tig) process. starting from the parametric optimization of tig welding process parameters (based upon taguchi design), welded joints were produced for functional validation. the output parameters selected for controlling the sensitization were selected as hardness and tensile strength of welded joints. the results are supported by sem analysis. further the study suggests that the tig welding process was found to be under statistical control (at optimized settings suggested by taguchi design) as regard to sensitization of welded joint is concerned.
