Effect of PWHT and Electrical Parameters on Austenitic Phase, Sigma Phase and Corrosion in Duplex Steels S32205

open access: yesEngineering Reports, Volume 8, Issue 4, April 2026.
Welding power and post‐weld heat treatment (PWHT) at 850°C influence phase transformations in S32205 duplex stainless steel, promoting sigma phase formation and reducing corrosion resistance. PWHT at 850°C also replicates HAZ‐like microstructures in base metal, enabling improved characterization of weld joint properties.
