“…e mechanical and microstructure properties were performed to examine ultimate tensile strength values and metal movement properties toward the welded FSW of the Al-Cu welded joint. e authors found at 2 tilt angles, at 105 MPa, high tensile strength was obtained and the fracture surface was found nearly closer to Al and obtained brittle formation [12]. Anbukkarasi and Kailas used AA2024 and pure copper workpieces of 5 mm thick buttwelded configurations for various tool offset positions, with plain, threaded tool geometry, and plate positions.…”

Friction Stir Welding (FSW) is a superior metal joining technique for joining similar and dissimilar metals. The various materials acceptable for the FSW techniques were magnesium alloys, mild steel, stainless steel, copper alloys, titanium alloys, aluminium alloys, etc. In this method, the frictional heat generated by the tool on metal workpieces was used for joining, and the workpieces were joined below the upper critical temperature. The substantial benefit of this technique is that it is capable of welding unweldable alloys by the conventional fusion welding method. The welding tool was rotated, traversed, and penetrated into the joint between two base plates. A suitable tool design with appropriate process parameters will result in high-quality welding on workpieces. In these experiments, the tools were designed with different pin profiles. The welding tools required for FSW are designed using SOLIDWORKS, and temperature distributions across the weld regions were analyzed using Ansys software. The fixture needed for FSW is fabricated according to machine requirements. The tool material used was hardened H13 steel, and the base plates were aluminium alloy 6101 and copper alloy C11000. The temperature distributions are noted in each trial during FSW of Al-Cu joints along the weld line region. Due to maximum temperature at weld joints, high ultimate tensile strength and impact strength were obtained at 1200 rpm tool rotational speed and 20 mm/min feed rate with the square pin profile of a hardened H13 steel tool. The obtained ultimate tensile stress (UTS) at joints was less than that of the base plates Al and Cu. The microhardness value was higher at the nugget zone than at the base plates, giving high strength at the joint area and unevenly distributed.

“…79 Jupri et al found the highest joint strength at 2° tilt angle that allowed good Al-Cu flow in NZ. 80 Influences of tool tilt angle are as follows: The correct tilt angle ensures that material stirred by the tool pin is retained by the tool shoulder and pushed from top to bottom and front to back under the FSW tool. With the aid of the tilt angle, plastically deformed material is compressed under the FSW instrument. Within the stir region, the tool tilt angle allows the plasticized material to flow in both horizontal and vertical directions. The defects are filled by forging material downward due to large tilt angle A greater tilt angle produced a tighter weld and reduced the flash effect. As the axial plunge force is increased, a higher tilt angle allows Cu to freely flow in Al. Consequently, there is excellent metallurgical bonding between Cu and Al. The formation of massive and different forms of intermetallic increases the joint hardness due to high heat input in the stir zone at a wide tilt angle. Hence, the selection of optimum tool tilt angle is also necessary.…”

Aluminium (Al) and copper (Cu) are widely employed in the industry due to their significant corrosion resistance and electrical conductive properties. The simultaneous requirement of different special properties has increased the trend of joining of Al and Cu. The joining of dissimilar materials has arisen as a new challenge in the research field in the past decade. Friction stir welding (FSW) is a very worthy process to join metals that aren't the same. This article delves into the intricacies of FSW to join compatible metals such as Al and Cu. The various parameters of FSW, namely tool design, tool pin offset, rotation speed, welding speed, tilt angle, and different types of welding joints, are highlighted in this article. It also goes through the different types of defects, microstructures, and intermetallic compounds (IMCs) that are formed during Al-Cu FSW. The electrical behavior and corrosion behavior of the weld zone in Al-Cu FSWed joints were also reviewed. Role of interlayer in some emphasis was also given to form effective joints.

“…With an increase in tool rotational speed and the tool offset at the center and AA6101 side, the UTS value increases. At higher speeds, the tool offset towards the C11000 side, and the UTS value decreases [40][41][42][43].…”

In the present study, the evaluation of FSW input parameters on output response ultimate tensile strength (UTS) of the friction stir welded AA6101-C11000 joint is in agreement. The response surface methodology (RSM) was adapted for generating the mathematical regression equation to predict the UTS and to develop the FSW parameters to attain the highest UTS of the FSW joints. The central composite design (CCD) method from RSM with five levels and three factors, i.e., tool rotational speed, feed rate, and tool offset used to conduct and minimize the number of tests. During FSW, base sheet cu (hard metal) was stationed on the advancing side (+1 mm, +1.68 mm tool offset) and the base sheet Al (soft metal) on the retreating side (-1 mm, -1.68 mm tool offset). The radiography studies were accomplished to inspect the internal flaws of the FSW joints (Al-Cu).The XRD and SEM investigation of the ruptured specimens during the tensile test to evaluate the IMCs phase anatomy and fracture analysis. The maximum UTS value measured during the experimental work was 142.69 MPa at 1000 rpm, 40 mm/min, and -1.68 mm tool offset. The highest joint efficiency obtained was 82% compared with the AA6101 UTS value. RSM adapted for this work was 92% accurate and satisfactory.
