“…It is shown in Figure 8 that the channel width remains approximately constant during channeling using MFSC process. Rashidi et al 14 studied the material flow around the tool pin body using weakened broken tool pin technique. They demonstrated that the channel width forms because of the detachment of deposited shear layers of material from tool pin body behind the pin.…”

In this study, the two geometry tools, including straight cylindrical pin and upward conical pin, are used to create channel in monolithic plate of Al 5083 alloy using the modified friction stir channeling technique. The channeling process was done under different directions including linear and non-linear channeling paths. Using upward conical pin caused easy channeling under non-linear paths, increase in height and hydraulic diameter of channel, and improvement in channel structure. As a result, in modified friction stir channeling technique using both tools, the shape of channels was stable and constant along the different channeling paths. However, the channel size was changed along the different paths. Along the vertical and straight paths, the characteristics of channel were stable and constant during the channeling process. Existing results were also achieved along the curve direction when the advancing side was along the inner curve. Nevertheless, when the advancing side was along the outer curve, the values of channel characteristics were varying at the various locations of the curve path. The stop-action technique and observations on the cross section of channels were utilized to explore the variations of channels and the channeling mechanisms along different paths. It was found that the variations of channel properties were because of the location of the displacement of shear layers along curve and the amount of extracted material by tool pin along the curve paths.

Friction stir welding (FSW) is widely used to join different grades of aluminium alloy but for steel material it requires high speed rotation of FSW tool which develops high temperature on tool. This review paper is concerned with the effect of temperature in the FSW process and heat generation by the high speed of rotation on the FSW apparatus. The other parameter has also studied to show the effect on FSW tool in stir welding process. In this work different research papers and their work are presented. The variety of work on stir welding process is discussed by hypothetical analysis on past performance.

“…Rashidi et al [4] claim that the stability of the channels can be solved using a non-threaded tool probe because this has the ability of maintaining the material flow constant during the process. Another study was published by Rashidi et al [7], investigating the material flow using the broken tool probe technique in order to understand the channel formation. In 2019, Pandya et al [8] have used X-ray micro computed tomography and optical microscopy to study the material flow during the FSC process.…”

In the present investigation, constant position and constant force process control modes; and representative process temperature measurements were analysed during the application of the friction stir channelling process. The experimental tests were carried out using rolled plates of AA5083-H111 with thickness of 15 mm. Results show that the FSC process was found not stable during the forward traverse movement stage when it is performed via position control. For both control modes, the tool was subjected to a more severe loading during the initial plunge than during the channelling period. Moreover, it was found that the tool vertical position is not significantly affected during the channelling stage when the process was force controlled. From the temperature measurements carried out, it was recorded a maximum process temperature of about 330°C.
