Abstrakt: This study's objective is to experimentally examine how welding current affects the mechanical characteristics and microstructure of 6 mm thick stainless steel 304L austenitic plates that have been welded using Tungsten Inert Gas (TIG) welding. Three welding different currents: 140 A (sample F1), 160 A (sample F2), and 180 A (sample F3). The results showed that the tensile strength and elongation of specimen F3's weld were around 586 MPa and 40.5%, respectively, and that these values were greater than those of the F2 and F1 weld samples. On the other hand, increasing the welding current resulted in a lower weld hardness value. For specimens F1, F2, and F3, the obtained values of hardness were 92, 88, and 84 HRB, respectively. 180 A is discovered to be the ideal current welding for TIG welding of 304L s. s., which can be recommended for several industrial applications.
