What is PWHT Effects on Corrosion in Welded Steel about?

This paper investigates the impact of post-weld heat treatment (PWHT) on the corrosion resistance and microstructural properties of electric arc-welded mild steel. Results indicate that PWHT, particularly normalizing, enhances corrosion resistance while balancing mechanical properties, whereas tempering may increase hardness but also corrosion rates due to carbide precipitation. The findings suggest that industries should adopt normalizing as the preferred PWHT method for mild steel in corrosive environment
