Friction stir welding is increasingly being considered as a bonding technology, especially for aluminum alloys for low temperature applications. The justification for low temperature application is made possible by the storage of liquid hydrogen as a potential fuel storage. In the research work, the bonds created by the partner institutions (Sweden- University West- Dr Vivek Patelt) are examined, with special regard to the residual stress state and the crystallographic orientation. The results of the microstructural test, combined with the results of the mechanical material test, greatly facilitate the optimization of the bonding technology and the safe introduction of aerospace and automotive applications. During the research, we used the examination devices in the institute as X-ray diffraction residual stress, computer tomography,  EBSD orientation and classical metallographic methods.
