Comparative Study on meChaniCal performanCeS of CirCular and flat Geometry WeldS in friCtion Stir WeldinG of aluminium alloyThis study is to find the extent of variation in mechanical properties between plate and pipe welds fabricated out of the same FSw process parameters. Common thickness of 3 mm along with similar tool specifications is used to fabricate the weld. Process parameters of tool rotational speed 2000 rpm and weld speed 94 mm/min that was defined as optimal for pipe weld is used as common process parameters. welds are analyzed for hardness and tensile properties. Yield strength and ultimate tensile strength varied about 8.1% and 11.2% respectively between plate and pipe welds. The hardness of the stir zones varied about 11.6% between plate and pipe welds.

“…Regarding linear FSW, there is vast research and published work on successfully joining diverse aluminum, magnesium [61], copper, titanium [62][63][64], and steel [65][66][67][68][69][70] alloys, as well as dissimilar materials. However, as expected, published work related to OFSW is much more limited, although there are reports of successful welds on tubular specimens, mainly composed of aluminum [22,37,42,49,[71][72][73], steel [17,45,74], titanium [63], copper, magnesium, or zinc alloys, and also dissimilar materials (AL3003 and pure copper) [40]. FSW/OFSW performed on aluminum alloys that are considered nonweldable, such as the AA6XXX series, tend to be the main focus material of published work, which is understandable given the superiority of FSW/OFSW over the fusion methods for these alloys, filling an industrial "void" after so many years.…”

Friction stir welding is a solid-state joining process widely used in several industrial applications. One of its variants, orbital friction stir welding, is of key importance in fundamental industries such as oil and gas and aerospace. For orbital friction stir welding, there is a need to develop not only new process parameters but also tools and ancillary mechanisms that can ensure sound, high-performing joints are obtained. This review assesses the current state of orbital friction stir welding, highlighting several key aspects related to this technology.

“…Lammlein et al [100] used the FSW process to join 106.68 mm diameter Al alloy 6061-T6 pipes with a wall thickness of 5 mm and reported to achieve 70% strength that of the base metal. Ismail et al [101,102] studied the efect of tool rotational and weld speeds over the tensile strength of AA6063 pipe joints. Tey obtained high-strength joints of 126 MPa under optimum values of welding parameters (a rotational speed of 1500 rpm and a welding speed of 1.8 mm/s).…”

The permanent metal joining processes play a vital role in assembling the complex aluminium structures of the aerospace, automotive, marine, and oil industries. The invention of friction stir welding (FSW) redefined the mechanism of metal joining to produce high-quality welds by eliminating the consumption of electrodes and shielding gases, resulting in economical processes. Research works still lack to explore the application of FSW in complex geometries. In this view, the present work reports a critical review of various geometries welded by FSW, mainly circular geometries that are majorly used in the oil and gas industries. The various aspects of the FSW of pipes, such as process facilitation, process parameters, tool material selection, and tool design selection are discussed. The paper also presents insights into the parameters responsible for the weld quality, the feasibility of optimization techniques, and the status of various fixture arrangements. The facilitation requisites for FSW of pipes are also provided based on the reviews made. The review concludes by discussing the challenges associated with the FSW of pipes, economic aspects, and future research directions.
