“…By increasing the plunge depth, the joint between the two specimens will be stronger in this case also depending on the thickness of the plate used and the tool. Then the longer the friction between the tool and the specimen will affect the heat and the weld joint's quality [23]. Dwell time does affect the increase in tensile strength [24].…”

“…Many researches on micro Friction Stir Welding (µFSW) has been carried out for similar materials such as aluminum alloys [10]. There are several parameters to consider in µFSW, such as tool geometry, tool rotation, travel speeds, and downward force [23]. However, from several studies that have been carried out, µFSW research on spot joints with dissimilar materials between magnesium and aluminum has not been widely carried out.…”

Micro-friction stir spot welding (µFSSW) is one type of welding that is suitable for joining lightweight materials. One of the challenges in joining lightweight materials with µFSSW is that the material is easily perforated, or the join is not strong enough, so it is necessary to select the right µFSSW parameters. In this article discusses about investigates the micro-Friction Stir Spot Welding (µFSSW) parameters on weld geometry, mechanical properties, and metallography on dissimilar materials of AZ31B and AA1100. The material thickness of the AZ31B and AA100 is 0.5 mm and 0.32 mm, respectively. The µFSSW tool is made of high-speed steel (HSS) with a pin diameter of 0.25 mm and a shoulder diameter of 0.5 mm. The constant process parameters of the µFSSW joint used, i. e., plunge depth, dwell time plunge rate, and high tool rotational speed of 33,000 rpm. Welding test results include weld geometry, mechanical properties, and metallography. Weld geometry testing to determine the weld nugget diameter. The mechanical properties test was shear tensile test and cross tensile test, while the metallographic test included macrostructure and microstructure observations. The results of the FSSW weld geometry show that at a dwell time of 700 milliseconds and a plunge depth of 600 microns, the weld pin diameter and weld shoulder diameter are close to the pin diameter and the diameter of the shoulder tool used. Dwell time and plunge depth has a significant effect on tensile strength. The maximum shear and cross loads achieved were 387±17 N and 29±2 N, respectively. Intermetallic compounds (IMC) are observed at the interface of the two materials, while a dwell time of 700 milliseconds give the effect of cracks on the inside of the weld

“…The tool's rotational motion generates heat, and the resulting plastic deformation causes the diffusion of both the metals' atoms to join. Micro friction stir welding (μFSW) is a kind of friction stir welding that is used to combine materials with thick of less than 1000 μm (1 mm) (Sen et. al., 2019).…”

The usage of industrial robots in manufacturing industries has revolutionized the traditional manufacturing process into more diverse and sustainable modern manufacturing processes. This paper presents the design and analysis of a 6-DOF robotic arm, which will perform a highly précised micro friction stir welding process. Friction stir welding is a technology that is constantly evolving. It has played a vital role in connecting metals in numerous sectors since its invention in 1991, and one of the outcomes of its development is micro friction stir welding, which was invented in 2004. There are numerous advantages that a designed robotic arm possesses over other traditional micro friction stir welding machines, which include high precision, sustainability, flexibility, time, and cost-effectiveness, along with a small operation area. The robotic arm is designed in two phases; the first stage is a design of links and revolute joints, respectively, and high-speed motor selection for the end effector to operate at high torques with required precision and accuracy. In the second phase, the designed model was analyzed using ANSYS software. In this phase, the transient and structural analyses are performed to analyze the performance of the robotic arm under various conditions.

“…In friction stir welding, a non-consumable tool is used with especially designed pin which is plunged into and along the adjoining line of two pieces of the similar or dissimilar materials. Tool rotational speed, speed of welding and tilting angle are the main parameters which affect the joint properties in FSW [3][4][5]. Although FSW is a good welding process for Al alloys as it is free from many welding defects yet FSW of aluminium alloy decreases the mechanical properties significantly in the weld area due to partial annealing, overheating, overaging and coarse weld microstructure and wide heat affected zone (HAZ).…”

Friction stir welding (FSW) is extensively used to join aluminum alloys components for applications in structural, aviation and automotive sectors. In this investigation, the mechanical properties (tensile strength, percentage elongation, and microhardness), abrasive wear properties and microstructure of friction stir welded joint of AA6061-T6 were studied by inter-plate reinforcing of silicon carbide microparticles (µSiC) and silicon nitride microparticles (µSi 3 N 4). The friction stir welding was performed at different tool rotational speed (TRS) (750, 1000 and 1400 rpm) and welding speed of 56, 80 and 112 mm/min. The friction stir welded joint without reinforcement and with µSiC exhibited maximum tensile strength at two combinations of welding speed and tool rotational speed; one at welding speed of 112 mm/min, TRS of 1000 RPM and other at welding speed of 56 mm/min and TRS of 1400 rpm. It was realized that the reinforcement of µSiC and µSi 3 N 4 decreased the tensile properties of the welded joint but improved the abrasive wear and microhardness properties considerably in the stir zone. The reinforcement of µSiC during FSW demonstrated better tensile, microhardness and abrasive wear resistant properties than the FSW joints with µSi 3 N 4 reinforcement. The improvement in microhardness of the FSW joint reinforced with SiC and Si 3 N 4 microparticles is attributed to the pinning effect produced by the hard particles inclusions.
