TL;DR: In this article, the residual stress profiles in aluminum and steel welds, and in shot peened aluminium, obtained via synchrotron and neutron diffraction at the ESRF-ILL in Grenoble, were presented.
Journal ArticleDOI
Characterization of the influences of FSW tool geometry on welding forces and weld tensile strength using an instrumented tool
TL;DR: In this paper, the impact of tool parameters on forces during welding, on the tool torque and tool temperature were investigated using a systematic tool profile matrix which considered the influence of four variations of each of these six geometric factors.
Journal ArticleDOI
Optimising FSW process parameters to minimise defects and maximise fatigue life in 5083-H321 aluminium alloy
TL;DR: In this article, a systematic approach to optimising FSW process parameters (tool rotational speed and feed rate) through consideration of frictional power input is presented, and it is shown that rotational speeds are the key parameter governing tool torque, temperature, frictional powers and hence tensile strength and fatigue performance.
Journal ArticleDOI
Effect of process parameters on the residual stresses in AA5083-H321 friction stir welds
TL;DR: In this paper, the effect of varying welding parameters on residual stress profiles in friction stir welds of aluminium alloy AA5083-H321, which were created on a fully instrumented friction welding machine, was determined non-destructively using synchrotron X-ray diffraction.
Journal ArticleDOI
Weld tool travel speed effects on fatigue life of friction stir welds in 5083 aluminium
TL;DR: In this article, the influence of weld tool travel speed on the occurrence of "onion-skin" forging-type defects in single pass friction stir (SP FS) welds was investigated.
