Fatigue Behaviour of Al 6082-T6 Friction Stir Welded Tubular Joints under Torsional Loading
The aim of the present research is to investigate the fatigue behaviour of friction stir (FS) welded tubular joints in aluminium alloy subjected to torsional fatigue loading. To manufacture the samples which were tested, an MTS I-STIR process development system was equipped with a retracting tool specifically designed for these tubular welds. Al 6082-T6 FS welded samples were tested under cycli...
متن کاملTHERMAL STABILITY OF FRICTION STIR PROCESSED ULTRAFINE GRAINED Al-Mg-Sc ALLOY
Two different aspects of the thermal stability of grains were studied – (i) thermal stability of grain structure evolution during friction stir processing (FSP), and (ii) thermal stability of grains after FSP. It was concluded that Al3(Sc,Zr) dispersoids are effective in limiting grain growth to ultrafine grained regime (UFG) by stabilizing the microstructure during FSP. The presence of these d...
متن کاملAutomatic seam-tracking of friction stir welded T-joints
In this research, a method for implementing automatic seam-tracking for friction stir welding, referred to hear as WeaveTrack, is presented. In this extrumum-seeking control technique, the tool weaves back and forth during welding to maintain the location where axial force is greatest, which is shown to be the center of the weld. Results demonstrate the effectiveness of this technique in tracki...

متن کاملSeam-Tracking for Friction Stir Welded Lap Joints
This article presents a method for automatic seam-tracking in friction stir welding (FSW) of lap joints. In this method, tracking is accomplished by weaving the FSW tool back-and-forth perpendicular to the direction of travel during welding and monitoring force and torque signals. Research demonstrates the ability of this method to automatically track weld seam positions. Additionally, tensile ...
