<br/><br/> 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
