  This article deals with the dissimilar joining of two different grade Cr-Mo steel (2.25Cr-1Mo: P22 and modified 9Cr-1Mo: P91) for power plant application. The dissimilar butt-welded joint was produced for conventional V groove design by using the gas tungsten arc welding (GTAW) process with the application of an ERNiCrMo-3 Ni-based super alloy filler. A microstructure characterization was performed to measure the inhomogeneity...

  In the present work, the relationship between microstructure and mechanical properties has been investigated for the dissimilar welded joint of P92 steel and Inconel 625, fabricated using the pulsed current gas tungsten arc welding (GTAW) process. Microstructural investigation revealed that the pulsed current resulted in fner equiaxed dendrites in the bulk weld metal, while columnar dendrites were observed in the weld metal near...
