The aim of this paper is to investigate the microstructure and mechanical properties of 304L stainless steel joints using Gas Tungsten Arc (GTA) welding. To investigate these three different electrodes of stainless steel such as 308L, 430L and 2209 are used as continuous filler metal for welding. Besides this tensile and impact specimens are prepared to evaluate the mechanical properties of the welded joints as per ASTM standard. GTA weld microstructures are presented by optical microscopy with various magnifications of weld metal region. The values obtained for ultimate tensile strength, yield strength, hardness, percentage of elongation and surface morphology for the welded joints are then compared with the data obtained. From this investigation, it has been found that the joints fabricated by 2209 stainless steel filler metal shows superior mechanical properties when compared to the joints fabricated by 308L and 430L stainless steel filler metal.
