Nowadays, friction stir spot welding (FSSW) is becoming a serious candidate technology to
join aircraft materials such as AA2024-O and AA6061-T6 since the use of FSSW offers …

Aluminum (Al) and copper (Cu) have been widely used in many industrial fields thanks to
their good plasticity, high thermal conductivity and excellent electrical conductivity. An …

The defect formation mechanism during friction stir welding (FSW) was investigated by the
three-dimensional visualisation of material flow around a tool. The three-dimensional flow …

The present paper focuses on the role played by a Zn interlayer in the improvement of the
mechanical behavior of Al-Cu Friction Stir Spot Welds. An unusual configuration of lap joint …

Stir zone galling, excessive deformation and degraded weld strength are attributes of friction
stir spot welds with excessive flash. In an attempt to determine the critical expelled flash …

In recent years, the increasing application demand for Mg alloys in automobile, rail transport,
aviation and aerospace industries brings about the growing prominence of seeking reliable …

Ultrasonically assisted friction stir welding (UAFSW) was explored. Metallographic structures
and material flow prepared by UAFSW were compared with those prepared by conventional …
