چکیده مقاله
In this study, the effect of filler metal on the microstructure and mechanical properties of dissimilar joint API X52/X65 was investigated Welding was performed by tungsten gas arc method with four filler metals ER 80SNi1, Inconel 82 ERNiCr 3 , Inconel 625 ERNiCrMo 3 and ER2209 Microstructural observations showed that ER80SNi1 ferrite austenitic weld metal, Inconel 625 austenitic original phase with scattered precipitations in the grain boundaries, ER2209 has a two phase structure consisting of ferrite and austenite layers and Inconel 82 weld metal has a highly interstitial microstructural structure The mechanical properties of the joints were investigated using microhardness and impact tests at ambient temperature The presence of duplex and ferrite delta structures in the weld metal ER2209 increased its microhardness compared to other weld metals Also, ERNiCr 3 weld metal was less hard than other weld metals due to its austenitic and coarse structure The results of impact test showed the highest and lowest fracture energies of 233 and 144 joules, respectively, for the weld metalobtained by welding with filler metals ER80SNi1 and ERNiCrMo 3
