“…In particular, a systematic bibliographical investigation was carried out to collect fatigue results generated by testing specimens made of 6056-T4, 6061-T6, 6082, 6082-T6 and 6082-T4. These specimens had been manufactured using different combinations of the key welding process parameters [18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The thickness of the FS plate in these data ranged from 0.8-7 mm and the fatigue testing used load ratios of -1, 0, 0.1, 0.2, and 0.5.…”

After developing a bespoke FS welding technology suitable for joining aluminium tubes, some one hundred welded tubular specimens of Al 6082-T6 were tested under pure axial, pure torsional and biaxial tension-torsion loading.The influence was explored of two independent variables, namely the proportional or nonproportional nature of the biaxial loading and the effect of axial and torsional non-zero mean stresses. The experimental results were re-analysed using the Modified Wöhler Curve Method (MWCM), with this bi-parametrical critical plane approach being applied in terms of nominal stresses, notch stresses, and also the Point Method. The validation exercise carried out using these experimental data demonstrated that the MWCM is applicable to prediction of the fatigue lives for these FS welded joints, with its use resulting in life estimates that fall within the uniaxial and torsional calibration scatter bands. The approach proposed in the present paper offers, for the first time, a complete solution to the problem of designing tubular FS welded joints against multiaxial fatigue loading.
