Friction-stir-welding (FSW) technology has been growing since it was patented in 1991 at TWI. Since then the majority of research and industrial applications for joining aluminium alloys were made on wrought aluminium alloys. Lately several investigations have been done in FSW of dissimilar alloys. FSW also has a big potential in the casting industry - especially in high-pressure die casting (HPDC). In this article an investigation of a FSW dissimilar joint made from a casting aluminium alloy (AA413.0) and technically pure aluminium (AA1050) was done. This kind of joint can be used to make an assembled casting, joined with FSW with the aim to have a casting with different material properties or to join HPDC with FSW to assemble a casting with inner cavities. %26lt;br%26gt;In this article the temperature distribution of the FSW joint of a cast aluminum alloy and technically pure aluminum is investigated. In the experimental work several FSW parameters were tested: the tool speed, the tool rotation and the position of the tool regarding the joint center. During joining the temperature was measured with a thermocouple and the temperature distribution in steady state was calculated with the FEM program Sysweld. The microstructure and mechanical properties of the joint were investigated.
