“…The peak temperature occurred at around 180 degrees Celsius. The value of the temperature has an agreement with the temperature measurement of friction welding of A6063 and 304 L stainless steel reported in [23]. The estimated peak temperature from ANSYS results is also comparable to the experimental result with an error of 7.06 %.…”

workpiece is produced as a solid-state joining process. The heat is generated at the weld interface because of the continuous rubbing of contact surfaces, which, in turn, causes a temperature rise and subsequent softening of the material. Eventually, the material at the interface starts to flow plastically and forms an upset. When a certain amount of upsetting has occurred, the rotation stops and the compressive force is maintained or slightly increased to consolidate the weld. Aluminum 6061 and AISI 304 are materials that are widely used in the construction field. The investigation of the CDFW process for Aluminum 6061 and AISI 304 was limited. Aluminum is a lightweight metal and resistant to corrosion. Unfortunately, aluminum is difficult to be joined by welding due to having a high heat conductivity. Therefore, studies are aimed at determining the thermal cycle profile and the shape of the flash in CDFW welding by computer simulation and experimental methods to improve the strength of CDFW joints.

“…To acquire a good quality joint, it was necessary to generate a high temperature over the whole surface of the rod, starting from the axis and ending on the periphery. Some of the best results were obtained for the conical surfaces, in which a much more even temperature distribution was observed in the joint cross-section than on the flat surfaces [33]. In [34], it was proven that altering the contact surfaces of the joined rods not only improved the connection, but also deteriorated the mechanical properties of the joint to a lesser extent.…”

The article focuses on the Direct Drive Rotary Friction Welding of ultrafine-grained copper rods, which feature increased mechanical properties and good electrical properties, yet are limited in size. The use of UFG metals is often limited by the too small dimensions of semi-finished elements produced by SPD methods. Therefore, the production of finished machine parts from UFG metals is currently economically unjustified. Dismissal of dimensional limitations can be done by introducing joining to technological processes. The proposed joining method does not lead to a melting of the material in the joining zone or excessive degradation of the UFG microstructure. To obtain the best results, the research used the method of low-energy welding of two kinds of specimens: with a flat or a conical contact surface. In the article, the authors present, by means of metallographic microsections and microhardness measurements, the influence of rotational speed, welding pressure and conical shape contact surface on the quality of the obtained joints. The conducted research made it possible to obtain good quality joints whose microhardness is reduced only by about 10% in comparison with the base material and the tensile strength dropped from only 397–358 MPa.

“…RFW has also been used to join stainless steel to other materials. RFW was used to join this material to nonferrous metals such as copper [6][7][8][9][10], Inconel [11,12], titanium [13][14][15], and aluminum [16][17][18][19].…”

Due to the different properties of the materials, the fusion welding of dissimilar metals may be difficult. Structural irregularities may form as a result of various phase transformations during welding. Solid-state welding, as opposed to fusion welding, occurs below the melting temperature. As a result of the melting and solidification phenomena that happen in fusion welding, solid-state welding is expected to reduce the potential for phase transformation. This paper describes the use of a rotary friction welding technique to join carbon steel and 304 stainless steel. The purpose of this work is to investigate the characteristics of rotary friction welding (RFW) when joining 304 stainless steel to carbon steels with different carbon contents. Experiments were carried out on the RFW of low- and medium-carbon steels with 304 stainless steel. The investigation was carried out using the Taguchi method of experimental design. The joints’ tensile strengths and microstructures were evaluated. The parameters that had the greatest influence on the tensile strengths of the welding results were identified. The combination of parameters resulting in the greatest tensile strength is also suggested. A microstructural examination of the weldment revealed mechanical mixing and interlocking.
