With more and more attention to the technology of tailor welded blanks (TWBs), it is vital to study the springback of TWBs. In this paper, the springback law of parallel and perpendicular to the weld of TWBs hyperboloid shallow shell affected by blank holder force, punch string height, and the difference of blank thickness was researched by finite element software. The results show that: by means of drawing and trimming, the springback of TWBs can be reduced, and the curvature of TWBs is less parallel to the weld, but the curvature is larger perpendicular to the weld. The effect of blank holder force on the trimming springback is relatively small in the range of experimental date. With the punch string height increasing, the drawing and the trimming springback are both increased firstly and then gradually decreased perpendicular to the weld, and the drawing and the trimming springback are both decreased parallel to the welding. And perpendicular to the weld, with the increase of the quadratic difference of thickness, the drawing springback of the thinner side is gradully decreased, and the drawing springback of the thicker side is gradually increased, after trimming, the springback of the thinner and the thicker side are both less than the drawing springback, and parallel to the weld, the drawing and the trimming springback are decreased firstly and then increased with the increase of the quadratic difference of thickness.
