“…To prevent gaps in the metal workpiece during the welding process, clamps are used to secure the workpiece. By using higher-quality clamps and constructing a fixture specifically designed for friction-stir welding, the weld can be produced with greater precision and accuracy [2]. The fixture was specifically designed to only work with unique structures, ensuring that it produces welds of the same type.…”

Friction stir welding is an innovative welding technique that joins two different materialswithout the need for consumables. The process involves a profiled probe and shoulder toolthat is rotated and plunged between the two workpieces at the interface during the friction stirprocess. The weld zone undergoes dynamic recrystallization, resulting in a strong bondbetween the materials. This method offers superior bonding compared to traditional arcwelding. In the context of conventional or non-traditional milling machines, friction stirwelding is performed. It is necessary to use a milling fixture to attach the plates that need tobe butt and lap welded, fixture can be used in underwater FSW. To ensure the workpiece issecurely held in place, a fixture or holder is necessary. In this article, friction-stir welding,and a fixture with a clamping setup are constructed. The fixture is carefully designed toconsider the movement of the instrument and workpiece, and it is manufactured usingCatiaV6 3D experience software. The fixture is then subjected to three different types oftesting using Simulia software. The materials tested include cast iron, die steel, and tool steel.After simulation analysis, the best material for friction-stir welding operations is selected.

“…Aluminum alloy (AA 7075) has been more popular in the automotive, aerospace, and aircraft sectors in this current era due to its good ratio of strength to weight, ductility, cracking resistance, corrosion resistance, and harsh environments [3]. During the FSw process, the workpiece material is mechanically stirred by the high rotational speed tool and undergoes intense plastic deformation at a higher temperature generated due to the friction, which extends to beyond the agitation zone (thermo-mechanical affected zone).…”

The effecT of DifferenT conDiTions on The Tensile ProPerTies of AA7075-T6 DuringThe fricTion sTir WelDing Process in this paper the investigation of the FSw result characteristics on AA7075-T6 of the highest grade is carried out using different process parameters. A vertical milling machine with different FSw tool geometry is used to weld AA7075. when the tool rotational speed varies from 1200 and 1800 (rpm), different welding parameters are studied, the plunge depth of tool is between 0.14 and 0.20 mm, the table transverse speed range is between 20 and 50 (mm/min) and the tool shoulder diameter was 20 mm. The welding settings are optimized using the Taguchi approach. in this experimental investigation Taguchi Technique is utilized in this study to optimize three factorial and three level designs. The results show that when the rotating speed increases, the uTS of the welded joint increases, whereas the tensile strength of the welded joint decreases resulting to frictional heat created during the FSw process. Tensile strength decreases as feed increases and increases as rotational speed increases. For a 5 mm thick plate, tensile strength is optimal with a tool shoulder diameter of 20 mm, a rotational speed of 1600 rpm, feed rate of 30 mm/min and plunge depth. The shoulder diameter of 20 mm provides the maximum ultimate tensile strength when it is compared with all other tool shoulder diameter. The Al alloy AA7075-T6 plates, however, concurrently developed an equiaxial grain structure with a substantially smaller grain size and coarsened the precipitates.
