This paper deals with experimental investigation of stress corrosion cracking of stainless-steel grade 304 after GTAW welded under simulated environment corrosion. Specimens welded in 60 and 65 Ampere used 5 and 10 L/mnt of Argon shielding gas. Constant tensile load test 4000N and immersed specimen were conducted for 24 hours in Hcl+Aquades solution result variety crack characteristics. After testing, an orange-colored layer of corrosion was seen covering the entire surface. This layer causes corrosion resistance for a certain period of time so that the corrosion process stops. The parameter ampere and shielding gas flow rate affected the crack that occurs. The results of the photo of the microstructure show cracks with the model trans granular at surface and intergranular after crack insert to grains boundaries. Vickers Hardness and Microstructure used to evaluate of welding area. The Lowest ampere of welded result maximum rough crack from surface and The Highest ampere result smooth crack on all of surface.
