What is PWHT Effects on Mild Steel Corrosion 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. The study finds that normalizing treatment optimally balances improved corrosion resistance and mechanical properties, while tempering may increase hardness but decrease corrosion resistance due to carbide precipitation. Recommendations include adopting normalizing as the preferred PWHT method in corrosive environments and further research on tem
