“…A post-weld heat treatment (PWHT) factor analysis (temperature range of 200-400 • C for 1 and 4 hrs, speed of 950 rpm, axial force of 2.3 kN, and tilt angle of 1 • ) was conducted for a threaded conic tool on the microstructure and corrosion behavior at the NZ of AZ31 Mg alloy sheets [67]. The grain sizes of 470 µm and 776 µm after 1 hr and 4 hr holding time corresponded to the temperature range of 300-350 • C. Corrosion resistance increased with a decrease in grain size.…”

This review reports on the influencing parameters on the joining parts quality of tools and techniques applied for conducting process analysis and optimizing the friction stir welding process (FSW). The important FSW parameters affecting the joint quality are the rotational speed, tilt angle, traverse speed, axial force, and tool profile geometry. Data were collected corresponding to different processing materials and their process outcomes were analyzed using different experimental techniques. The optimization techniques were analyzed, highlighting their potential advantages and limitations. Process measurement techniques enable feedback collection during the process using sensors (force, torque, power, and temperature data) integrated with FSW machines. The use of signal processing coupled with artificial intelligence and machine learning algorithms produced better weld quality was discussed.
