Background of the Researches Increasing concern with fuel consumption leads to widespread interest in lightweight structures for transportation vehicles. Several competing technologies are available for the structural connections of these structures, namely welding, mechanical fastening/riveting, and adhesive technologies. Great interest is dedicated to welding of lightweight structures, particularly because of economic reasons derived of part count reduction, faster and cheaper fabrication, and possible weight gains. However, drawbacks of welding include variation of properties in the weldment area, intrinsic metallurgical difficulties possibly leading to unacceptable defects, as well as, from a mechanical design point of view, possibly detrimental fatigue behaviour features associated with the continuous path of crack propagation. Crucial factors for the application of new technologies are the cost. Especially for the substitution of metals by light weight alloys beneath all technological properties of the economic aspects have to be considered. Currently the technological processes receiving more widespread interest in metallic lightweight structures are laser beam welding (LBW) and friction stir welding (FSW). According to E.Schubert, M. Klassen ET. AL Light weight components are of crucial interest for all branches that produce moving masses. The aim to reduce weight has to be accompanied by high production efficiency and component performance.
