Abstract: | Tailor welded blanks (TWBs) offer an excellent opportunity to reduce manufacturing costs, decrease vehicle weight, and improve the quality of sheet metal stampings. The car makers are trying also to decrease as much possible the needed time from a car concept to that car on the market. For this reason the tool able to give the required shape to the tailor welded blanks must be designed and optimized in shorter time. In comparison with homogenous blanks, tailor welded blank imply more disturbing elements like: welding line, HAZ, different strength or thickness of the joined materials. All this elements must be taken in consideration in design and optimization of tools for tailor welded blanks stamping. |
