Combined Binder Force and Temperature Adjustment for Weld Line Movement Control in Stamping with Tailor-Welded Blanks

This paper introduces a new method to assist deep drawing of tailor-welded blanks with combined restraining force control and binder temperature control. The effect of variable flange temperature and blank holding force on the formability and weld-line displacement of aluminum tailor-welded blank was studied through Finite Element Analysis using LS-DYNA PC.
