Zusammenfassung:	In this study, the mechanical properties of welded austenitic stainless steel plates type AISI 316L are carried out using stress strain microprobe in welded region, and heat affected zone. Automated metal inert gas welding process has been used. Different heat inputs are selected in order to describe the effect of metallurgical aspects on mechanical properties like ultimate tensile strength, yield strength, and hardness. The results showed that the heat input 305 J/mm provides maximum strength, and hardness value. This can be attributed to formation of delta ferrite phase and its shape, which subsequently changes the mechanical properties.
