In the last decade, the friction stir welding of polymers has been increasingly investigated by the means of more and more sophisticated approaches. Since the early studies, which were aimed at proving the feasibility of the process for polymers and identifying suitable processing windows, great improvements have been achieved. This owes to the increasing care of academic researchers and industrial demands. These improvements have their roots in the promising results from pioneer studies; however, they are also the fruits of the adoption of more comprehensive approaches and the multidisciplinary analyses of results. The introduction of instrumented machines has enabled the online measurement of processing loads and temperature, and critical understanding of the principal aspects affecting the material flow and welds quality. Such improvements are also clearly demonstrated by the increase of the strength of recent joints (up to 99% of joining efficiency) as compared to those reached in early researches (almost 47%). This article provides a comprehensive review of the recent progresses on the process fundamentals, quality assessment and the influence of process parameters on the mechanical behavior. In addition, emphasis is given to new developments and future perspectives.

The effects of tilt angle (TTA), plunge depth (TPD) and offset (TO) of tool in friction stir welding of poly(methyl methacrylate) T-joint were investigated. To understand better the effects of process parameter, thermomechanical simulation of joint was assessed. The results seem to show that at higher TPD and TTA, frictional heat increases. Woven tissue structure joint line forms after friction stir welding of poly(methyl methacrylate) sheets. The distance of woven layers was affected by TPD and TTA, while TO do not significantly affect heat generation of joint. The best material flow and adequate heat are generated at 0 mm TA, 2° TTA and 0.2 mm TPD, respectively. The highest flexural and tensile strength of friction stir welded joint were approximately 93% and 90% of as-received poly(methyl methacrylate), respectively. Crack forking was detected on the fractured surface of flexural samples and crack path was detected in the vicinity of shrinkage holes at fracture surface of tensile samples. These holes and degradation of poly(methyl methacrylate) during friction stir welding process decrease strength and hardness of the joint.

The emerging trends in advanced robust manufacturing trend need light and medium weight materials with higher strength for different purposes. The aluminum and copper alloys are the major construction material for different causes in aerospace, railway and shipbuilding industries. Joining of dissimilar material during built-up structures is one of the tough tasks of the manufacturer; joining of similar and dissimilar material can be effectively made in the Friction Stir Welding (FSW). In this research article made an attempt to find an optimal process parameter for lap joining process in FSW for Al 5052, Al 6061 joining with copper. The finite element simulation model of the lap joint designed, analyzed and simulated with consideration of various spindle speed of CNC machine, an optimal speed condition found and which is applied in during the manufacturing. The fabricated workpieces were tested and the results were compared with the simulated model result, it shows that the fabricated dissimilar materials workpieces are superior to the simulated results especially in tensile load conditions.
