چکیده انگلیسی
This paper describes the development of a semi-automated friction stir welding (FSW) technique for joining 38Â mm nominal outer diameter (OD) tubes of 6082-T6 aluminium alloy with 3.5Â mm nominal wall thickness. The technique incorporates a retracting tool in order to avoid leaving a substantial hole in the joint line after extracting the tool at the end of the welding process. This is one of very first applications of FSW to small diameter tubular geometries to be reported in the open literature and the technique is capable of producing small-scale production runs (circa 100) of welded tube specimens with consistent tensile and fatigue properties. The tensile strength of the extruded 6082-T6 tube was 303Â MPa while the joint efficiency of the weld was 0.55 both for complete tube specimens and for microtensile specimens. This compares well with values reported in the literature for 3Â mm flat plate specimens of 6082 alloy.
