That method takes extra steel, secondary processes, time and money. At ArcelorMittal Tailored Blanks, our capabilities allow all the engineering to be done BEFORE stamping.
We can laser butt weld two or more separate steel shapes together to make one piece. Most Laser welded blanks (LWB) are made from two unique pieces but some are made from six or more different blanks.
This allows us to put the thickness, strength or corrosion protection only where it's needed. The part is then stamped and no secondary processes are necessary.
Some examples of a tailored blank include:
- Door inner needs to be thicker in the hinge attachment area
- Front rail, rear rail, B-pillar or full door ring – softer grade or lighter gauge in the area of first/greatest impact. This absorbs energy. Then within the same part, we transition to stronger or thicker areas which prevent intrusion. This saves lives.
