Rotary Friction Welding of Inconel 718 to Inconel 600

Abstract: Nickel-based superalloys exhibit excellent high temperature strength, high temperature corrosion and oxidation resistance and creep resistance. They are widely used in high temperature applications in aerospace, power and petrochemical industries. The need for economical and efficient usage of materials often necessitates the joining of dissimilar metals. In this study, dissimilar welding between two different nickel-based superalloys, Inconel 718 and Inconel 600, was attempted using rotary friction welding. S… Show more

“…The severe plastic deformation during friction welding imparts a high number of lattice defects in the form of a dislocation network in the weld zone. The presence of the strain energy and higher temperatures have resulted in the dynamic recrystallization of the deformed grains, and fine equiaxed grains are produced in the weld zone [ 19 , 20 ]. The average grain sizes of the base metal and weld metal are 46 ± 7 µm and 20 ± 2 µm, respectively.…”

“…A continuous drive rotary friction welding (ETA Technology, Bangalore, India) machine with a loading capacity of 150 kN was used in the present study (refer to Figure 1). The experimental procedure corresponding to the continuous drive rotary friction welding machine has been detailed elsewhere (Rehman et al, 2021).…”

“…With compressive and heat forces on both surfaces until the meeting of the two materials can reach the melting temperature, the welding process occurs [3]. Friction welding can be used to connect a variety of materials [4][5][6][7], provided that one of the components to be welded has some rotational symmetry, the solid surface makes it easier to do welding, the goal is to get a good quality welded joint [8].…”
