“…The welding process was performed with a constant travel speed ( V ) of 20 mm min −1 , and different rotation speeds of 1250 and 1600 rev min −1 . The selected rotation and travel speeds result in a higher heat input compared to the values reported in the literature for FSW of annealed copper [26-38]. These values were selected to achieve satisfactory weld in the SPD-treated samples which need high heat input due to the enhanced strength gained during CGP.…”

Friction stir welding (FSW) was performed at different tool rotation speeds of 1250 and 1600 rev min−1 on both annealed, and severely plastic deformed copper sheets via constrained groove pressing (CGP). Also, the effects of water cooling during FSW on weld properties of CGP-treated samples were investigated. It is found that the heat-affected zone (HAZ) has a lower hardness value than the corresponding base metal due to the large grain growth. While the stir zone (SZ) shows a finer grain size with a higher hardness. Moreover, the results proved that in-process water cooling can effectively reduce grain growth in HAZ of CGPed samples and improve the weld strength by increasing the minimum hardness to about SZ hardness of the annealed sample.

“…They noted a 70 % improved tensile strength in the parameter combination, such as a rotational speed of 1000 rpm and a welding speed of 50 m/min. Nagesh et al [6] welded dissimilar materials, such as copper and brass, using the FSW process. They compared the results of FSW, such as tensile, hardness, and the impact strength of dissimilar welding strength with parent metal welding, to explore the detailed nature of welding.…”

Copper metal matrix composites (CMC) are broadly employed in various applications in the fields of space, aviation, automobile and electronics industries. The welding of CMC in using conventional methods is very difficult and expensive due to its crystallographic nature. Friction stir welding (FSW) is a more prominent and reliable technique for welding than conventional methods. Therefore, this work is based on work with CMC material, which is prepared with a stir-casting technique. Pure copper (Cu) is reinforced with tungsten (W) and boron carbide (B4C) particles in different combinations and welded using the FSW process to study the mechanical and micro-structural properties. Multi-objective decision-making methods, such as the technique for order preference by similarity to ideal solution (TOPSIS) and grey relational analysis (GRA) are used to find optimal parameter combination. The experiments are planned according to the L 18 orthogonal array (OA) using the most influential parameters, such as reinforcement the percentage of B4C, tool rotational speed, welding speed, and axial force. The performance of outcomes is measured based on the responses such as tensile strength, hardness, and impact strength of the weld joint. Based on the results 15 % of B4C reinforcement, 900 RPM rotational speed, 15 mm/min welding speed and 6 kN axial forces are optimal for better mechanical strength in the welding with TOPSIS and GRA techniques. Additionally, scanning electron microscopic image (SEM) analyses were carried out for better understanding of weldments’ microstructure changes.

“…Using this method, it is possible to join a wide range of materials and make dissimilar joints [41]. Apart from aluminium alloys, the studies proved that copper, titanium and magnesium alloys, as well as steel and polymers [42][43][44][45][46][47], could also be joined. Iwaszko and Kudła [48] successfully performed a friction stir processing (FSP) process on a Cu/SiC composite.…”

The purpose of the following study was to compare the effect of the shape of a tool on the joint and to obtain the values of Friction Stir Welding (FSW) parameters that provide the best possible joint quality. The material used was an aluminium alloy, EN AW-3004 (AlMn1Mg1). To the authors’ best knowledge, no investigations of this alloy during FSW have been presented earlier. Five butt joints were made with a self-developed, cylindrical, and tapered threaded tool with a rotational speed of 475 rpm. In order to compare the welding parameters, two more joints with a rotational speed of 475 rpm and seven joints with a welding speed of 300 mm/min with the use of a cylindrical threaded pin were performed. This involved a visual inspection as well as a tensile strength test of the welded joints. It was observed that the value of the material outflow for the joints made with the cylindrical threaded pin was higher than it was for the joints made with the tapered threaded pin. However, welding defects in the form of voids appeared in the joints made with the tapered threaded tool. The use of the cylindrical tool resulted in higher values for about 37% of mechanical properties compared with the highest result for the tapered threaded joint. As far as the parameters were concerned, it was concluded that most of the specimens were properly joined for a rotational speed of 475 rpm. In the joints made with a welding speed of 300 mm/min, the material was not stirred properly. The best joint quality was given for a rotational speed of 475 rpm as well as a variety of welding speed values between 150 and 475 mm/min.
