Experimental Investigation of Weld Charcteristics in Friction Stir Welded Joints Aa 6082-T6 Aluminum Alloy by X-Ray Radiography

Aluminum alloy 6082-T6 aluminum alloy (Aluminum–Silicon–Magnesium) has gathered wide acceptance in aerospace and automotive industries. In this novel, research work specially designed tool pin profiles were employed in order get defect-free sound weldments with good mechanical and microstructural properties. The aim of studying the present research work is to investigate the weld quality of AA 6082-T6 aluminum alloy weldments using friction stir welding (FSW) process with four different geometrical tool pin probes, namely MX-TRIVEX™, A-SKEW™, three flat threaded, and MX-TRIFLUTE™ concave shouldered tools with three different rotational speed’s (1000, 1200, 1400 rpm’s) at single traverse speed (25 mm/min). X—Ray radiography technique has been carried out to study the weld defects like lack of penetration, lack of fusion, worm hole, and cracks of weldments through MXR-451/26 make machine as per ASME Sec-IX 2017 QW 191. From this experimental study, it was found that influence of tool rotation speeds like 1000, 1200, and 1400 rpm on temperature and quality of aluminum alloy 6082-T6 weldments.
