چکیده مقاله
In this study, the fracture toughness of weld metal in API 5L X90 micro alloy steel joints was investigated Welding was performed using filler metals ER120 S G, ER100 S G and ER90S B3 by GTAW process Microstructural studies were performed using light microscope and SEM scanning electron microscope Microstructural studies showed that the base metal microstructure includes ferrite and granular bentite While different welding metals all contain different amounts of needle, polygonal ferrites and islets of martensite / austenite MA The highest amount of needle ferrite was observed in ER120 S G welding metal The toughness of base metal and weld metals was determined by Sharpe impact test The test results showed that the weld metal ER120 S G at ambient temperature and 20 ° C, has the highest fracture toughness compared to other weld metals Keywords:Component
