More than 35 million tailor-welded blanks will be stamped by the North American automotive industry in 2000. These multi-gage, multi-strength blanks present a variety of new challenges to the metal forming community. Practical considerations in weld quality, blank design, die design, part handling techniques, and forming behavior in the stamping of these increasingly accepted blanks are addressed in this paper. While tailor welded blanks are adding well-recognized value to the automotive industry, the unique features of tailor welded blanks (multi-gauge, multi-strength, weld quality, etc.) impose a variety of new considerations on the stamping plant operation. Awareness, understanding, and acceptance of these unique features are essential starting ingredients in a successful stamping operation. Even in the absence of any weld quality issues the fundamental forming limitations of tailored blanks require greater attention to part design, die design, material properties, and press operation. The ability of the stamping plant to understand and overcome these increased forming challenges will determine the amount of added value that tailor welded blanks will bring to the auto company's overall manufacturing operations.
