Patchwork Blanks

Reaching Targeted Strength by Means of Local Reinforcement

In the automotive industry added steel parts reinforce the stampings by being welded to the stamped part after stamping. Patchwork Blanks allow straight to the point strength precisely at the desired location. Additional blanks, so called Patches, are attached to the parent blank by either spot welding or laser welding. Parent Blank and Patch then can be stamped together without any problems. The use of Patches pays off. The automotive industry saves money, weight and effort early on in the assembly process of the body-in-white, because attaching additional reinforcements is avoided.

Double advantage: the combination with patches allows to tap the full cost and weight reduction potential of Tailored Blanks.
