Abstract：

The stamping formability of non uniform thick tailor welded blanks(TWBs)is quite affected by the weld seams and its orientation as well as the ratio between the thin sheet and the thick sheet.In this paper,effects of welding techniques on the formability of TWBs,such as laser welding,seam welding and TIG welding,are discussed.Deep drawing of semi spherical shells and square cups is carried out,the non uniform deformation behaviors and the movement of the weld seams are summarized.
