“…Meanwhile, the material transfer models under conventional FSW and SSFSW processes are displayed in Figure 3. Moreover, the stationary shoulder effectively prevents the plasticized materials overflowing out of the SZ and then reduces the size of flashes, while much more materials can flow into the SZ [25,26]. The instantaneous cavity can be filled with the abundant plasticized materials.…”

In order to improve joint integrity and reduce the amount of intermetallic compounds (IMCs), 6061-T6 Al and AZ31B Mg alloys were successfully joined by stationary shoulder friction stir welding (SSFSW). The stationary shoulder effectively enhanced the joint surface integrity and reduced the thickness reduction of the Al/Mg joint. The elimination of pin adhesion was beneficial to increasing material transfer and then improving interfacial joining length of Al/Mg joint. Extremely thin IMCs layer could be achieved because of the heat sink induced by the stationary shoulder. The maximum tensile strength of the Al/ Mg joint reached 137 MPa at a welding speed of 60 mm/min, rotating velocity of 1000 rpm and offset to Mg sheet of 0.3 mm, which was 130% higher than that of conventional joint. SSFSW is feasible and has the potential to join dissimilar materials with the formation of IMCs, such as Al/Mg alloys, Al/copper alloys, Al/titanium alloys and so on.

“…In the case of metal-composite joints, the metal is generally positioned below the composite laminate. The rotating probe stirs against the metal surface leading to the formation of hooks that fastens the two components [9,10,41], as depicted in Figure 13a. A variant of the process that involves the direct deposition of polymeric material through fused deposition modeling (FDM) has been recently developed to avoid the use of a pre-prepared stud [8].…”

Multi-materials of metal-polymer and metal-composite hybrid structures (MMHSs) are highly demanded in several fields including land, air and sea transportation, infrastructure construction, and healthcare. The adoption of MMHSs in transportation industries represents a pivotal opportunity to reduce the product’s weight without compromising structural performance. This enables a dramatic reduction in fuel consumption for vehicles driven by internal combustion engines as well as an increase in fuel efficiency for electric vehicles. The main challenge for manufacturing MMHSs lies in the lack of robust joining solutions. Conventional joining processes, e.g., mechanical fastening and adhesive bonding involve several issues. Several emerging technologies have been developed for MMHSs’ manufacturing. Different from recently published review articles where the focus is only on specific categories of joining processes, this review is aimed at providing a broader and systematic view of the emerging opportunities for hybrid thin-walled structure manufacturing. The present review paper discusses the main limitations of conventional joining processes and describes the joining mechanisms, the main differences, advantages, and limitations of new joining processes. Three reference clusters were identified: fast mechanical joining processes, thermomechanical interlocking processes, and thermomechanical joining processes. This new classification is aimed at providing a compass to better orient within the broad horizon of new joining processes for MMHSs with an outlook for future trends.

“…5–7 In order to achieve a suitable welding method without the need for fillers, the friction-stir welding (FSW) method was invented and rapidly developed to create a homogenous welding area, minimize the effects of heat shocks on the workpiece, work without the need for external heat source, and prevent from physical and chemical changes in the material, while providing desired mechanical properties. 8,9 The FSW method is a new method invented by The Welding Institute in 1991. In FSW, boiling heat is caused by friction between the tool and the workpiece.…”

In recent years, the growing trend of using polymer materials in various industries has led to significant improvements in the methods of production and bonding of polymer materials. The present study aimed to optimize the flexural strength of polypropylene sheets welded by the friction-stir method, which is considered as one of the most efficient methods in this field. The surface quality and mechanical properties of the components produced in this method highly rely on the parameters of rotational speed, linear speed, geometry, and tool tilt. Therefore, this research seeks to evaluate the effect of these parameters on three different levels, both experimentally and statistically, in order to investigate the welding flexural strength. By applying the analysis of variance and Box–Behnken response surface methodology, the results revealed the existence of a significant relationship between the properties and parameters of the process and the possibility to examine the effect of the interaction of different parameters in the process using mathematical modeling and Chart analysis. In addition, optimal models were introduced through process optimization so that the flexural strength of the weld joint was increased by up to 96% of that of the base specimen, after conducting further experimental tests, resulting in confirming the optimal model. Finally, the efficiency of the designed model was evaluated by comparing the measurement errors obtained from the experimental results and the prediction of the model.
