Obtaining perfect dissimilar welding joints which are exposed to corrosive environments still a problem up to now. The ASTM A36 and 316L stainless steels dissimilar metals were joined by means of Capacitive Discharge Welding (CDW). The welding parameters such as distance between metals, pressure, applied energy, and surface parameter were kept constant. The FeCl2 corrosive solution concentration also kept constant at 0.5M. The temperature of the solution was controlled at varied temperature, those are: 30 °C, 40 °C and 50 °C respectively. The resistance to the Stress Corrosion Cracking (SCC) load, was evaluated by time to fracture for certain dead tensile load and corrosive media. The SEM EDS data were retrieved to have deep insight of the SCC mechanism. The results show that, with 10 °C increasing temperature the SCC Threshold is decreased by 40% which are supported by the data of time to failure for certain load and also the SEM EDS. © 2025, Universitas Muhammadiyah Magelang.
