An Experimental Study of Effect of Welding Parameters on T- Weld Joint in TIG Welding of SS 316L and Development of its Microstructure and Mechanical properties

The microstructure and tensile strength of T weld joint of stainless steel 316 material in TIG (tungsten inert gas) equipment was analysed by varying shielding gas ( argon gas and Carbon dioxide) and voltage. Vastly different microstructures are formed in 316L stainless steel joints welded with Argon and Carbon dioxide and by varying voltage, respectively. Different microstructures, yield strength, tensile strength and weld bead hardness are tested in my project. Effect of varying voltage and shielding gas on stainless steel 316 material T-weld joint are analysed.
