Tailor-welded blanks (TWBs) are considered one of the important manufacturing methods. By which, a single blank with multi-sheets with different thickness, material, surface conditions, grade, or strength is produced. In this paper, the formability of TWBs is investigated. The base metal used for this study is aluminum (Al-1050) with different thicknesses. A several thicknesses of base metal for instance 0.6, 0.8, 1.0, and 1.2 mm are combined. A different thickness ratio (TR) of sheets combination of TWBs i.e., 1.25, 1.33, and 1.5 is considered. The TWBs are welded using friction stir welding (FSW) technique. A different working condition for instance rotational speed and travel speed is used in this investigation. The TWBs specimens are drawn into flangeless cups. The limiting thickness ratio (LTR) and mechanical properties of base metals are determined. Several experiments are carried out to investigate the optimal working conditions. The experimental results are discussed and presented. A validation of the experimental results using Tagushi approach to verify the optimal welding parameters is presented.
