“…However, the low values of elastic limit (YS) are recorded for values of S between 220 and 340 / mm min , and T between 2.4  and 2.6 . All these findings turned out to be in good agreement with those obtained by Wim Van et al [25] who indicated that the appearance of defects depends on the choice of the tilt angle. They found out that the best mechanical properties are obtained for the optimal tilt angle value of 2  , which makes it possible to obtain the best mechanical properties.…”

Friction stir welding (FSW) is an extremely complex process because it depends on the intrinsic and extrinsic factors of the material under consideration. The purpose of the present work is to formulate a set of recommendations concerning the choice of the different factors that are likely to influence the quality of the FSW joint and to find a mathematical model that allows predicting the mechanical behavior of the junction. An experimental design was therefore used to highlight the effect of the welding parameters on the behavior of the aluminum alloy FS-Welded joint. The most influential parameters were shown to be in the order of rotational speed, feed rate and tool tilt angle. The study of the interactions between these different parameters made it possible to establish a number of combinations of the different factors for the purpose of achieving the quality optimization of the FSW joint by obtaining a tensile strength of the weld joint equal to of that of the base metal.

“…They also found that the optimum FSW process window is wider for higher axial force, as shown in Figure 4. Van Haver et al [63] studied friction stir welding of aluminium high-pressure die castings, EN AC-46000 or also called EN AC-Al Si9Cu3(Fe). Although AC-46000 is difficult for fusion welding, it had been successfully welded by friction stir welding.…”

Aluminium castings have been widely used in many industries, including automotive, aerospace, telecommunication, construction, consumer products, etc., due to their lightweight, good electric and thermal conductivity, and electromagnetic interference/radio frequency interference (EMI/RFI) shielding properties. The main applications of aluminium castings are in automotive industry. For lighweighting purposes, more and more aluminium castings are used in the automotive vehicle structures to reduce weight, improve fuel efficiency, and reduce greenhouse gas emissions. However, due to the features of cast aluminium, such as porosity, poor surface quality, a tendency toward hot cracking, and low ductility, joining these materials is problematic. In this paper, the joining technologies for aluminium castings and the related issues, mainly cracking and porosity, are reviewed. The current state-of-the-art of joining technologies is summarized, and areas for future research are recommended.

“…Among these researches, the FSW of precipitation hardened aluminium alloy have special attention [3][4][5][6][7][8][9][10][11][12]. Many experiments conducted in the past dealt with seeking relationships between process parameters and resulting joint integrity [13] while others undertook studies in defining suitable operating windows [14,15]. Relationships between process parameters and weld defects have also been studied [16,17].…”

“…Gap tolerance and its bridge-ability has been given attention in the past but without close consideration on the influence of varying the tool profiles, process parameters and the welding sequence in FSW. The presence of pin re -entrant features influences the pulsating stirring effect [13][14][15]. When welding two abutted plates in FSW, the presence of gap between the faying surfaces of the plates is a reality and common problem for manufacturing reasons.…”

This paper presents research work conducted to experimentally establish the process response of two diverse shaped tool-pin profiles for friction stir welding (FSW) AA6082-T6 aluminium. The dwell time was optimised by plunging each tool-pin into a plate sample until the spindle torque stabilised thus ensuring sufficient plasticised material in contact with tool shoulder and the tool-pins. The welds were conducted by employing the optimised dwell time, which in turn revealed a minimised process response time and distance to reach weld stability with respect to (1) the force exerted on the tool-pin in the welding direction, Fx , and (2) the spindle torque, T, during the welding process. Both Fx and T stabilised well within the set (pre-determined) ramp-up distance of 20 mm, indicating that the effective (useful) weld length is maximised. The macrographs also revealed good dynamic material flow within the nugget zone regions and more evident in the nugget zone of the flared tool.
