“…[5][6][7][8][9] Since the early 1970s, research on friction welding of dissimilar materials has been increasing, including research on the determination of optimum conditions, the application, and the strength of friction welding. [10][11][12][13][14][15] Chromium molybdenum (SCM440) structural alloy steel is widely used in mechanical parts that require durability such as shafts, gears, and nuts. At the same time, Inconel steel (IN718) has excellent corrosion resistance and heat resistance, and its strength hardly deteriorates even at high temperatures.…”

“…Co. Ltd., Hanzhong, Shaanxi, China) continuous-drive rotary friction-welding machine (maximum of 45 kW and 320 kN forging load). According to our preliminary experiments and the literature on 304SS RFW [5,6,9,14], the welding experiments were conducted using welding parameters in which the welding pressure varied from 40 MPa to 200 MPa, rotational speed varied from 500 rpm to 2300 rpm, and welding time varied from 4 s to 20 s, all while under forging pressures of 100 MPa, 120 MPa, 140 MPa, 160 MPa, 180 MPa, and 200 MPa, respectively. During the RFW process, the welding power was recorded by a computer through an A/D converter with a sampling time of 0.01 s, and the surface temperature of the joint was measured by an infrared thermal imaging instrument (Tec VarioCAM@hr, head-HS Infra, Dresden, Germany) with a sampling time of 0.02 s. The data collected by the infrared thermography instrument had been calibrated using the data that thermocouple collected, and the emissivity of 304SS was determined to 0.8.…”

“…Figure 1 shows the location of the experimental equipment and the diagram of the temperature-detected area. joint; thus, it has a significant effect on the notch tensile strength and impact toughness [9]. Moreover, the overall width of the weld zone reduces with the increase of rotational speed [10].…”

“…The heat is generated by conversion of mechanical energy into thermal energy at the joint interface due to rotation under pressure. Friction welding involves thermo-mechanical working those results in grain refinement of the weld zone [3]. This welding method is characterised by low heat input, material save and an easy application.…”
