Abstract

The purpose of this article is to research temperature field during friction stir welding (FSW). Experimental FSW of 2 mm sheets was provided for temperature determination. Aluminum alloy AW 6082 was chosen as a material for workpieces. Temperature was measured by thermocouples. Influence of the tool rotation speed on temperature distribution was estimated using experimental results. An analytical heat source model developed before was improved; capability of the model in comparison with experiment was proved. The temperature distribution was calculated by means of numerical simulation. The simulation model was compared with experimental result. The results of numerical simulation are in good agreement with experimental results. Maximum temperature distribution along and across the weld centreline was estimated using developed FE-model.
