Tungsten Inert Gas welding is also known as Gas Tungsten Arc Welding (GTAW), has an advanced arc welding process become a popular choice when a high level of weld quality or considerable precision welding is required. However, the major problems of the TIG welding process are its slow welding speed and limited to lower thickness material in a single pass. In this work, autogenous TIG welding has been performed on 5 mm thick Duplex Stainless Steel 2205 plate without using any filler material. The wide selection of welding current and scan speed has been tested for getting full penetration welding. Activated flux has conjointly been used to improve the weld depth. After performing welding by maintaining the different gap between the plates to be welded, weld bead geometry and tensile strength of the weld has been investigated. It is observed that by maintaining an appropriate gap full penetration welding of the plate is possible which gives strength almost similar to the base material.
