“…He examined three tool geometries and discovered that due to higher heat input, the tool with a concave shoulder and a taper probe with three grooves generated more uniform stir zones than the other tools. Yuvaraj et al [16] made an attempt to analyze the role of tool axial force on mechanical behaviour of friction stir welded AA7075-T651 and AA6063-T6 joints. Four different axial load conditions were employed to fabricate the joints.…”

Many military and light weight aircraft designs call for joints between two different grades of aluminium alloy. This present study looked at the effect of tool shoulder diameter and tool pin profile on the tensile strength properties of dissimilar aluminium alloy AA6061-T6 and AA7075-T651 joints created by friction stir welding. The joints were fabricated utilizing three distinct tool shoulder diameters 15mm, 20mm and 25mm along with two distinct tool pin profiles namely taper and square. The microstructure and microhardness of weld stir zone (WSZ) were examined and linked with the strength parameters of the joints. Adequate frictional heat generation from 20mm shoulder diameter and pulsating stirring action of square pin revealed the formation of very fine grains in the weld nugget zone (WNZ). Due to enhanced material flow and the production of a defect-free stir zone, the joint created using a tool with a 20 mm shoulder diameter and square pin profile had the maximum hardness of 117 HV and the highest tensile strength of 284 MPa. The ductile mechanism of fracture is revealed by the presence of fine dimples accumulating in the tensile fractured surface of the joint fabricated by 20mm tool shoulder diameter and square pin.

“…Their research aimed to determine the optimal value of axial force. Sabry et al, [16], investigated the impact of rotation speed, clamping torque, and clamping pith on the mechanical parameters of the weld joint between AA6061, explicitly focusing on the advancing side. It was discovered that the maximum ultimate tensile strength (UTS) is attained when there is 30 mm, 1800 rpm, and 70 Nm for the take-into-consideration parameter range for the Clamp Pitch, rotational speed, and Clamping Torque, respectively.…”

Friction stir welding (FSW) is a solid-state welding method that involves joining two workpieces by applying pressure and significant plastic deformation close to their melting temperatures. The impact of rotation speed, travel speed, axial force, maximum temperature, and tool wear in the friction stir welding (FSW) process is significant. The present study examines the impact of three specified variables on the maximum temperature, ultimate tensile strength (UTS), and tool wear of friction stir welding (FSW) of 6063-T6 and 6060-T6 alloys. Response Surface Methodology (RSM) has been employed as an auxiliary method. The total amount of material removed from the tool wear was found to be directly proportional to the rotational speed but inversely proportional to the travel speed and axial force. The increase in rotation speed leads to higher tool wear but reduces the surface roughness of the tool. The findings indicate that the parameter with the most significant impact on the maximum attained temperature is 1800 rpm rotation speed and 4 mm/min travel speed, I KN axial force.
