The present work aims at exploring a new processing approach, 'Hybrid Manufacturing (HM)' technology for net-shape production of monolithic structures for the transportation industry. The HM process combines friction stir welding (FSW) and forming in order to modify the properties of the preform to better meet design requirements and provide netshape products. This paper focuses on understanding the process behavior and the effects of various process parameters on the properties and integrity of the produced monolithic structure during production. Formability of the produced monolithic structures is evaluated through stretch forming process experiments. The results obtained offer an understanding of the effects of the important process parameters needed to produce quality monolithic structures that fulfill design requirements and service conditions
