“…Recently, developing studies were done about FSW of polymers like polyethylene (PE) (Arici & Selale, 2007;Arici & Sinmazçelýk, 2005;Aydin, 2010;Bozkurt, 2012;Mostafapour & Azarsa, 2012;Rezgui et al, 2010;Saeedy & Givi, 2011), HDPE (Bozkurt, 2012;Rezgui, Trabelsi, Ayadi, & Hamrouni, 2011;Squeo & Quadrini, 2009), polypropylene (PP) (Kiss & Czigány, 2007, 2012Panneerselvam & Lenin, 2013), acrylonitrile-butadiene-styrene (Bagheri, Azdast, & Doniavi, 2013), polyethylene-terephthalate-glycol (Kiss & Czigány, 2012b), and the polyamide Nylon 6 (Panneerselvam & Lenin, 2014). Those works can be divided in two categories, according to the type of FSW tool used, i.e.…”

In the current study, a numerical model based on Lagrangian incremental formulation was developed for friction stir process (FSP) of nylon 6 and nylon 6/ multiwalled carbon nanotube (MWCNT) composite to investigate the thermomechanical behavior of them (e.g. temperature, effective plastic strain distribution, material flow, and material velocity). For this purpose, FSP was used to disperse the MWCNTs among the polymer matrix of nylon 6, homogenously. The X-ray diffraction and scanning electron microscopy were used to investigate the properties of fabricated nanocomposite. The obtained results were then used to verify the objectives of numerical model. According to the results, the MWCNTs are separated from each other while passing the tool-pin due to high plastic strain applied on them and greater amount of the material accumulates in the AS of stirred zone after passing the tool-pin. Also, MWCNTs were homogeneously and straightly dispersed throughout the nylon 6. The straight and non-curved dispersion of MWCNTs results in growth of its reinforcement capability.

“…The effect of double passes of the tool [17] in the FSW of medium-density polyethylene eliminated the root defect but the joint strength was less than 90% of the base material. Mostafapour and Azarsa [18] reported a joint efficiency of 97% with a shoe-heating method. The effect of preheating on the FSW of ultrahigh molecular weight polyethylene [19] was investigated where the additional heat enabled the material to be easily stirred; and 89% joint efficiency was achieved.…”

“…Bagheri et al [16] investigated the main process parameters while joining ABS sheets by stationary heated shoulder called "hot shoe." Mostafapour and Azarsa [17,18] used heat-assisted FSW to join polyethylene (PE) sheets and found that, in this way, it is possible to achieve a tensile strength up to 95 % of that of the base material. Pirizadeh et al [19] developed a double-sided tool to eliminate two of the main defects on FSW welds, namely root defect and back slit from ABS welds.…”

Friction stir spot welding (FSSW) experiments were carried out on polycarbonate sheets to assess the influence of the tool geometry on the joining loads and material flow. An instrumented drilling machine was used to measure the plunging load and the torque developing during the process. Different tool geometries were tested involving the variation of the tool pin shape (cylindrical or tapered), diameter of the tool pin, and diameter of the tool shoulder. The analysis of material flow enabled understanding the behavior of the load and torque trends measured during the process, such as the presence of load peaks during the plunging phase and reduced values of the axial pressure during the process. It was discovered that the average axial pressure was higher during pin plunging (such value was mainly determined by the pin diameter) while it dramatically decreased (almost to 1.2 MPa) during shoulder plunging owing to the higher heating resulting from higher tangential speed. The pin taper angle had negligible influence on the plunging load and torque. The tool shoulder influenced the plunging load and torque while it produced a negligible variation in the average axial pressure. On the other hand, the pin diameter influenced both the process loads and the axial pressure.
