Microstructural Study of Welded and Repair Welded Dissimilar Creep-Resistant Steels Using Different Filler Materials

This study examines initial and repair welds between creep-resistant steels, P22 and P91, using ER90S-B3 and ERNiCrMo-3 steel-based and nickel-based filler materials, respectively. TIG welding with and without PWHT was applied. Microstructural evaluation revealed martensitic transformation in HAZ, d...
