TIG AISI-316 welds using an inert gas welding chamber and different filler metals: Changes in mechanical properties and microstructure
[EN] This report analyses the influence of the use of an inert gas welding chamber with a totally inert atmosphere on the microstructure and mechanical properties of austenitic AISI 316L stainless steel TIC welds, using AISI ER316L, AISI 308L and Inconel 625 as filler metals. When compared with the...

| Sumario: | [EN] This report analyses the influence of the use of an inert gas welding chamber with a totally inert atmosphere on the microstructure and mechanical properties of austenitic AISI 316L stainless steel TIC welds, using AISI ER316L, AISI 308L and Inconel 625 as filler metals. When compared with the typical TIC process, the use of the inert gas chamber induced changes in the microstructure, mainly an increase in the presence of vermicular ferrite and ferrite stringers, what resulted in higher yield strengths and lower values of hardness. Its effect on other characteristics of the joins, such as tensile strength, depended on the filler metal. The best combination of mechanical characteristics was obtained when welding in the inert gas chamber using Inconel 625 as filler metal. |
