Our smarter steel solutions
Shaped blanks (unwelded)
A tailored-shaped blank is a blank that has the shape as close as possible to the final part.
- Reduces the complexity of their stamping dies
- Increases productivity
- Reduces scrap rates
Patched blanks
A patch is a piece of steel that is welded directly to a main/bigger blank before stamping. Patched blanks are ideal for managing energy absorption helping automakers to meet crash test requirements.

Laser‑welded blanks
A laser‑welded blank (LWB) is an engineered steel sheet created by laser‑joining different grades or thicknesses of steel into one optimized component.
This advanced process places high‑strength material where crash protection is required and lighter, more formable steel where weight savings or shaping flexibility matter. The result is a stronger, lighter, and more efficient automotive part, produced with reduced material usage and minimal scrap.

There are other part consolidation solutions out there. But ArcelorMittal MPI is the only one that saves costs without sacrificing safety. The secret lies in our patented laser-welding technology: partial ablation. Stronger welds. Safer cars.
Press-hardened steel (PHS) is the gold standard in strength, crash performance and repairability – all without the high switching costs of alternative materials. Yet welds can become brittle if too much of the protective aluminium-silicon coating enters the joint.
Not with MPI. Our unique partial ablation technique removes a narrow strip of coating around the weld, leaving the rest intact. This is the only industrial process available today that guarantees the weld is as strong as the base material.
Dynamic test (like Charpy) gives you confidence in the results, confirming crash performance without the cost of full vehicle testing. This speeds up development time of new steel combinations and welding processes, while ensuring the safe crash behavior of new body designs.
