Tight competition characterizing automotive industries in the last decades has determineda strong research effort aimed to improve utilized processes and materials in sheet stamping. As faras the latter are regarded light weight alloys, high strength steels and tailored blanks have beenincreasingly utilized with the aim to reduce parts weight and fuel consumptions. In the paper themechanical properties and formability of tailored welded blanks made of a precipitation hardenablealuminum alloy but with different sheet thicknesses, have been investigated: both laser welding andfriction stir welding have been developed to obtain the tailored blanks. For both welding operationsa wide range of the thickness ratios has been considered. The formability of the obtained blanks hasbeen characterized through tensile tests and cup deep drawing tests, in order to show the formabilityin dependency of the stress condition; what is more mechanical and metallurgical investigationshave been made on the welded joints
