Effect of Pulsed Current on the Microstructure, Mechanical Properties and Corrosion Behavior of Ni-Based Alloy/Super Duplex Stainless Steel Dissimilar Welds

This work addressed the effect of pulsed current (PC) and pass number on the microstructure, mechanical properties and corrosion behavior of Incoloy 825/UNS S32750 welds. The alloys were welded using PC and continuous current techniques. Mechanical properties of the weldments were examined using hardness, Charpy and transverse tensile tests. General corrosion and pitting corrosion behavior of the weld metals were studied using potentiodynamic...
