摘要

Weldments were fabricated between Incoloy 800HT and P91 steel using ERNiCr-3, and ER505 filler materials by GTAW process. The ERNiCr-3 weld has to interface columnar and equiaxed dendrites whereas the ER505 weld has cellular dendrites. The ER505 weld / P91 steel base interface shows delta ferrite. Unmixed zone (UMZ) on Incoloy 800HT side and Type I and Type II zones were observed on P91 steel side of weldments. It was observed that with an increase in heat input, there was an increase in tensile strength of ERNiCr-3 weldments whereas there was a decrease in tensile strength of ER505 weldments. The impact energy of ERNiCr-3 welds was 96 Joules whereas ER505 welds had the impact energy of 178 Joules. Based on microstructure and mechanical properties, ER505 was found to be the ideal filler for joining of Incoloy 800HT to P91 steel than ERNiCr-3 filler.
