“…Nickel-based alloys are widely used in the construction of pressurized water reactors (PWRs), fast neutron reactors (FBRs), and fusion reactors [1,2]. The Inconel690 alloy is a common choice for manufacturing critical structural components in nuclear reactors, such as the reactor pressure vessel (RPV), steam generator tubes (SG tubes), nozzle safety ends, and tube seat penetrations [3].…”

The study focuses on investigating the relationship between the ultrasonic effect and microstructure of ultrasonic-assisted gas tungsten arc welding (UA-GTAW) Inconel690 alloy joints. The influence of ultrasonic vibrations on Inconel690 plates was examined, while also clarifying the distribution pattern of the ultrasonic effect across the plate. Furthermore, actual welding experiments were performed by varying the distance between the ultrasonic horn and the welding torch. The results revealed that there were changes in both grain growth direction within the weld zone and refinement effects achieved under different distances. The optimal refinement of primary and secondary dendrite arm spacing was observed at distances of 60 mm and 180 mm between the welding torch and ultrasonic horn. The hardness of weld zone reached 235HV1 when the distance between ultrasonic horn and welding torch is 180 mm.
