Continuous drive friction welding is a solid-state welding process that has been experimentally proven to be a fast and reliable method. This is a complex process; deformations in the viscosity of a material alter the friction between the surfaces of the pieces. All these dynamics cause changes in the vibration signals; the interpretation of these signals can reveal important information. The vibration signals generated during the friction and forging stages are measured on the stationary part of the structure to determine the influence of the manipulated variables on the time domain statistical characteristics (root mean square, peak value, crest factor, and kurtosis). In the frequency domain, empirical mode decomposition is used to characterize frequencies. It was observed that it is possible to identify the effects of the manipulated variables on the calculated statistical characteristics. The results also indicate that the effect of manipulated variables is stronger on low-frequency signals.

“…In this stage, heat is produced by applying forging pressure on the plastic material. During this stage, chemical interdiffusion occurs, and the plastic material continues to be expelled [ 18 , 19 ]. Figure 3 shows an image of a CDFW welded ASTM A35 rod.…”

“…Selvamani and Palanikumar [19] used ANOVA methods to establish empirical relationships between the process parameter combinations and process outcomes such as the tensile strengths and percentage of elongation of the welded joints. Senkov et al examined the process parameters of inertia friction welding and related them to welding process outcomes, especially from the point of view of the flywheel energy [20].…”

Friction welding is a promising technique for the welding of dissimilar metals. This study deals with the welding of two different alloys, namely, AISI 304 and AISI 1040. The welding process parameters, namely, friction pressure, friction time, forging pressure, and forging time were optimized for maximum tensile strength using a response surface methodology (RSM)-based technique and an adaptive-network-based fuzzy inference system (ANFIS) model. The predicted responses obtained using the ANFIS model were more accurate compared to those obtained using the RSM. From among the four input parameters examined in the study, the frictional pressure was found to be the most influential. The ANFIS model developed in this study shows significant promise as a predictive technique that can provide reasonable estimates of tensile strength for different welding parameters.

“…But it is difficult to use the traditional fusion welding method because of the tremendous difference in mechanical and metallurgical properties between dissimilar materials [5]. Continuous drive friction welding (CDFW), as the most promising method to join dissimilar materials, is importantly demanded in the manufacture of a new generation of aircraft, rocket, and shipboard equipment because of the advantages such as high material savings and low production time [6][7][8].…”

“…In previous works, dissimilar metals such as Al/Fe [6,7], Al/Ti [8], Al/Cu [9], Cu/Fe [4], Ti/Fe [10], and Cu/alumina ceramic [11] of the friction welding have been carried out by many researchers. In particularly, aluminum/steel [7] and copper/steel [12] friction welding joints present good performance with tensile strength higher than the matrix.…”

e dissimilar pure metals Al/Fe and Cu/Fe with different metallurgical compatibility were joined by continuous drive friction welding. e friction weldability was investigated. e microstructure of the joining interface was analyzed by scanning electron microscopy, and the chemical compositions were tested by energy-dispersive spectroscopy. e joining strength was evaluated by tensile test, and the fracture was detected by X-ray diffraction analysis. e results show that sound joints of Al/Fe and Cu/Fe can be obtained by continuous drive friction welding process. A discontinuous reaction layer was formed on Al/Fe interface, and no obvious reaction layer appeared on Cu/Fe interface. e tensile strength of the joints increased with increasing friction pressure, and the highest strength could reach up to 70 MPa for Al/Fe joint and 222 MPa for Cu/Fe joint. All the Al/Fe friction-welded samples failed at the friction interface, while the Cu/Fe joint under 36 and 44 MPa friction pressure failed at Cu matrix during the tensile test.
