Description
A device was designed and manufactured to facilitate accurate monitoring of forces, torque and tool temperature during friction stir welding (FSW) and for use as a weld quality indicator in relation to issues such as tool wear, lack of tool penetration, joint line gap and void formation. The "LOSTIR" device, comprising a general-purpose FSW tool, a tool holding system, a weld monitoring system and display software, was developed for retro fitting to a wide range of milling machines. Numerical modelling using CFD (computational fluid dynamics) codes was undertaken for process parameter selection. Instrumented welds were made to simulate quality control problems in FSW of AA-6082 and AA-2024 aluminium alloys.
