Fatigue and Static Properties of Friction Stir Welded Aluminium Alloy 6082 Lap Joints Using Triflute-Type and Smooth Tool

Abstract: Due to numerous advantages, the FSW process more and more frequently used in different industries. Presently 99% of the FSW applications are connected with welding of aluminium alloys and most of FSW connections are butt joints, for which the very good mechanical properties are proved in many research. Instead of butt joints also a few types of shape joints can be friction stir welded, e.g. lap joints, multiple lap joints, fillet joints and T-joints.This study presents the results of investigation into the imp… Show more

“…Thus, the very low advancing side fatigue strength of the CL6 welds has to be related to the presence of the sharp crack associated to the hooking defect. According to Krasnowski (2014), the presence of a hooking defect, aided by the oxides layer, also visible in Figure 5.e), generates favourable conditions for crack initiation, growth and propagation, conducting to the very low fatigue lives registered in Figure 13 for the CL6 advancing side samples.…”

“…This trend is not related to the alloy composition but it can be explained with the geometry conguration of the welds. In many article addressing the overlap conguration, e.g., [Eri05], [Inf+16], [Kra14], it was observed for the crack to originate always from the crack-like roots between the interfacing surfaces of the sheets. This defect is generally associated with a reduction of the eective sheet thickness thus a weaker cross section.…”
