EXPERIMENTAL STUDY FOR WELDING ASPECTS OF AUSTENITIC STAINLESS STEEL (AISI 304) ON HARDNESS BY TAGUCHI TECHNIQUE

Abstract

The objective of this research was to study influenceparameters affecting to mechanical property of austenitic
stainless steel grade 304 (AISI 304) with Gas Metal Arc Welding (GMAW). The research was applying Taguchi Method on
aaustenitic stainless steel (304) specimen of dimensions 110×40×3 mm, which have following interested parameters: arc
current at 150,200, and 250 Amps, gas flow rate at 10,20, and 30 kg/hr and arc voltage at 15, 20 and 25 Volt.The study was
done in following aspects: Hardness of Heat affected zone and Weld bead.
The present paper aims at the study of factors affecting to mechanical property of austenitic stainless steel with Gas
Metal Arc Welding (GMAW) at different welding parameters.
