Studies were carried out on three reference SS304 stainless steel plates and on two welded SS304 plates. An innovative EIS paste-based cell is employed for this purpose. The study investigates the impact of mechanical cleaning, citric acid+sodium hydroxide (CA), and nitric acid (NA) passivation on welded SS304 stainless steel plates. Welded systems in both the heat-affected (HAZ) zone and base metal (BM) are being analyzed before and after each treatment. Specifically, one welded plate underwent mechanical cleaning, another was solely subjected to CA passivation, and a third received both mechanical cleaning and CA passivation.
