Abstract
The presented work is devoted to an experimental determination of a non-stationary temperature field during friction-stir welding using a thermo camera and thermocouples respectively. The aim of the measurements was to tune up the heat source originating from friction between the rotating tool and a stationary probe by finding appropriate parameters of an employed mathematical model. After having identified the parameters, the friction-stir welding simulation was carried out using an aluminium alloy probe. Strain measurements were also performed during welding at selected locations on the probe. The experimentally determined results have been compared with the results of the numerical simulations.
