Abstract This work focused on comparing the effect of welding heat input within the range from 1 to 5 kJ/mm and filler metal on the Mo segregation within the microstructure due to welding of dissimilar weld joints of superaustenitic stainless steel/Incoloy 28 and duplex stainless steel/super duplex stainless steel and its effect on the mechanical and corrosion properties of the weld joints. The mechanical properties and pitting corrosion resistance were found very sensitive to formation of unmixed zone at fusion line and secondary phases within weld metal and HAZ such as NbC and secondary austenite which appeared in the microstructure after welding |
