“…As a result of the lack of bounding, the UTS decreases while the behavior of tensile strength and ductility mirror each other, resulting in a decrease in ductility [47]. A higher welding speed leads to inadequate and improper mixing of materials, and the cavity defect occurs in the SZ, which leads to stress concentration, decreases the loading area, and reduces the tensile strength [48,49]. On the other hand, the microhardness and tensile strength of the joint tend to increase as the welding speed decreases.…”

“…The shape of the stirring pin and shoulder [56] and the assembly gap of the plate [57] also affect the performance of the joint, as shown in Figure 2. The shape of the stirring tool influences recrystallization and grain growth behavior by affecting the heat input, force and torque, and material flow [48,58]. The presence of a gap in the plate reduces the material availability at the interface, which affects the heat input and material flow in the vicinity of the tool pin profiles.…”

Fusion welding causes joint deterioration when joining aluminum alloys, which limits the use of aluminum alloy components in high-end equipment. This paper focuses on an overview of how to achieve high-strength aluminum alloy welded joints using welding/plastic deformation composite forming technology. The current technology is summarized into two categories: plastic deformation welding and plastic deformation strengthening. Plastic deformation welding includes friction stir welding, friction welding, diffusion welding, superplastic solid-state welding, explosive welding, and electromagnetic pulse welding. Plastic deformation strengthening refers to the application of plastic deformation to the weld seam or heat-affected zone, or even the whole joint, after welding or during welding, including physical surface modification and large-scale plastic deformation technology. Important processing parameters of plastic deformation welding and their effects on weld quality are discussed, and the microstructure is described. The effect of plastic deformation strengthening technology on the microstructure and performance evolution, including the hardness, tensile strength, fatigue property, residual stress, and hot cracking of aluminum alloy welded joints, and its evolution mechanism are systematically analyzed. Finally, this paper discusses the future development of plastic deformation strengthening technology and anticipates growing interest in this research area.

“…The size and the no of particles of harder material are affected by the tool offset. Mirzaei and Hayati claimed that 2 mm offset to copper increases the number of hefty particles in the stir zone [21]. Esmaeili et al showed that the lamellar composite structure increases the tensile strength and the disappearance of this composite structure results in the reduction in tensile strength [20].…”

Friction stir welding has been successfully employed to fabricate dissimilar thickness AA1050 and oxygen free copper (Cu-OF).The highest value of the joint tensile strength obtained was 91% of the AA1050 alloy strength with the tensile fracture path on the aluminum side. At the Al-Cu interfacial microstructure, a layer of Al4Cu9 and Al2Cu intermetallic compounds (IMCs) with thickness of 2.2 μm to 0.26 μm was developed at different welding speeds. The voluminous IMCs have an adverse impact on the tensile characteristics of the joint. The IMCs (0.26 μm -0.77 μm) at welding speeds of 160 mm/min and 213 mm/min with 1 mm tool offset, has trivial effect on the tensile property. The mechanical property of the joint was significantly affected by the tool offset and welding speed. Image processing techniques such as Gaussian blur, histogram normalization and binarisation were utilized to understand the distribution of copper in the weld stir zone.

“…For all the trials, the hardness tester was set by the capacity of 1 kg and dwelling period of 10 s. The hardness test analysis was performed for the base plates and at the welded joint area. The test procedure and the specimens were prepared according to the code ASTM E-384 [21] [24][28].…”

Friction stir welding (FSW) is a nearly modern welding method with vital advantages over the conventional welding process, such as lower distortion, enhanced mechanical properties, and eco- friendly. In FSW, the joint characteristics mainly depend on heat development during the joining process due to its solid-state joining method. The basic principles of thermomechanical methods during FSW are unknown since it is a new metal joining method. In this investigation, the 2D and 3D models of the tools with different pin forms were designed using SOLIDWORKS. The ANSYS software was used to investigate the temperature distributions near the weld zones. The fixture was designed and made according to the machine conditions. The base plates used were AA6101 and C11000; the tool material used was the Hardened OHNS steel tool with square and circular pin form. The temperature values were measured in each trial while joining of Al-Cu base plates along the weld line. The results reveal that in the joint area, a trial with high temperature leads to high ultimate tensile strength (UTS) and Charpy impact strength (CIS). Made at tool rotation speed 1200 rpm and feed velocity 20 mm/min of Hardened OHNS steel tool with circular pin form. The obtained UTS value at joints was less than that of Al and Cu base plates. The microhardness value detected at the joint area was higher than the Al and Cu base plates, providing high strength, and irregularly dispersed.
