چکیده مقاله
In this study, the effect of filler metal on the microstructure of API 5L X65 welded steel joints coated with INCOLOY 825 superalloy produced by SMAW process was investigated Welding was performed using filler metals, ENiCrFe 3, ENiCrMo 3 in root passes and E7018 in surface passes by SMAW process FESEM optical and scanning electron microscope equipped with EDS analysis was used to study the microstructure of weld metals and joints The microstructural results showed that the structure of both Inconel 625 and 182 filler metals was completely austenitic and solidified with dendritic morphology Also, the microstructure of weld metal 7018 mainly consists of polygonal ferrites and grain boundaries, among which some Widmann Statten and Acicular ferritesare also observed
