Abstract

Friction Stir Welding (FSW) is a relatively new welding process, which was developed at The Welding Institute (TWI), United Kingdom, in 1991. FSW is a solid-state joining process, i.e. no melting occurs. The welding process is promoted by the rotation and translation of an axis-symmetric non-consumable tool along the weld centreline. Thus the FSW process is performed at much lower temperatures than the conventional fusion welding. Nevertheless the control of the temperature field is fundamental to guarantee a high quality joint. In the present work the temperature field during the welding process was measured using an infrared camera. The test was conducted on 6 mm thick 5754 H111 aluminium alloy plates, in bead on plate configuration, with constant tool rotation rate and feed rate. Furthermore a finite element model was implemented and validated on experimental measurement data to evaluate the temperature field also into the plate.
