This manuscript proposes an enhanced technique for the friction stir welding (FSW) of ceramic particle‐reinforced aluminium‐related metal matrix composites. The proposed technique is the joint implementation of both the Aquila Optimizer and Pelican Optimization Algorithm. This proposed method aims is to enhance the welding efficiency, quality, and overall performance of the weld joints. The test is conducted in an all‐purpose machine at cutting speeds that permit temperatures that are comparable to the FSW of stainless‐steel, aluminium alloys and copper. Reaction–diffusion studies are conducted to better understand the diffusion‐control process under tool wear, and the tool wear rate is determined by the length of the cutting tool's nose tip. Rotational speed at 10 mm/min is examined. SiC exhibits the highest performance of aluminium and stainless steel. As the fraction of SiC increases to 18%, the axial force and rotational speed of FSW also increase.

“…FSW processes may be applied for similar and dissimilar materials welding joints configuration. However, it has been generally documented that joint efficiency can improve mechanical properties and microstructure characteristics using FSW processes of dissimilar materials to those of the base materials [2]. Figure 1 shows that the FSW process employs a non-consumable rotating tool comprised of a shoulder, pin, or probe.…”

Friction stir welding (FSW) has an advanced technique in solid-state conditions that joins from different materials compared to the fusion welding process and is eco-friendly. This ignificant advancement involves aluminium (Al) alloys which facilitate the FSW of distinguished flow patterns in the weld zone. Technically, heat energy and stirred material resulted in softening areas, affecting joint efficiency, mechanical properties, and metallurgical characterisation. This paper has concerns comprehensively covering and summarising the development and application of the topic in different aspects of the performance and quality of the FSW welded joint. The proper tools can create sufficient heat under the shoulder for excellent performance to deal with the welding parameter. All these tools have their literature and journal, which extensive discussion.Furthermore, alloy positioning, defect formation,rotational speed and transverse feed are essential analytical tools for FSW to control the significant weld quality. Furthermore, the mechanical properties associated with microstructural evolution highly dependent on welding technique have remarkably contributed to product development. Finally, a previous study has shown the interest in the topic to enhance the knowledge for further investigation with emerging technology for future recommendations in the FSW discipline.

“…To overcome above disadvantages and shortcomings, researchers have optimized and improved welding process parameters and structure of the stirring head, but they all failed to achieve satisfying effect. According to recent studies, FSW assisted by external energies like laser [3][4][5], current [6][7][8], electric arc [9], induction [10] and ultrasonic wave [11,12] is an effective method to overcome abovementioned disadvantages and shortcomings. Compared with electric arc and induction, laser assisted FSW is superior for accurate control over heating zone and high energy utilization [3][4][5].…”

To verify validity of new method for preparing dissimilar metals with high melting point through double laser assisted friction stir welding (FSW), butt welding tests on dissimilar metals of TC4 and GH4169 were carried out by conventional FSW, single laser assisted FSW and double laser assisted FSW, respectively. Macroscopic morphology, microstructure and mechanical properties of butt-joint were analyzed. Results demonstrated that the conventional FSW surface is relatively rough, manifested by existence of many trims and rags, incomplete mixing of joint and dissimilar materials, as well as a certain proportion of pore defects. The single laser assisted FSW surface is even and smooth, manifested with few trims and rags. Compared with conventional FSW, the dissimilar material mixing is improved significantly, and there are few pores. The double laser assisted FSW surface shows the best quality, manifested by the fewest trims and rags. The mixing of dissimilar materials is further improved and the joint has good shaping, without obvious defects. Tensile strengths of joints of conventional FSW, single laser assisted FSW and double laser assisted FSW were 238 MPa, 423 MPa and 505 MPa, respectively. Laser assisted FSW has the higher tensile strength, which is attributed to the more complete material mixing and thicker layer of element diffusion. The laser preheating can decrease axial downward pressure of stirring head and radial stress of the stirring needle in the welding process significantly compared with those in conventional frictional stir welding. In particular, double laser preheating can make stresses on the stirring needle more uniform. This is conducive to mutual flowing and integration of dissimilar materials for FSW. Meanwhile, it can reduce the wearing loss between the stirring head and welding component. Double laser preheating can prolong service life of stirring heat significantly and it can improve welding speed significantly under the same rotating speed of the same stirring heat, thus enabling to increase welding efficiency.
