ArcelorMittal and TRUMPF collaborate on laser cutting for precise shaping of laser-welded hot-stamped parts

In response to the automotive industry’s increasing demand for lighter, safer, and more sustainable vehicles, ArcelorMittal and TRUMPF are partnering to combine ArcelorMittal’s expertise in advanced automotive steel with TRUMPF’s cutting-edge laser technology, enabling the precise shaping of laser-welded, hot-stamped MPI parts for modern vehicle design.

TRUMPF’s non-contact laser cutting process ensures burr-free edges and minimal waste, while reducing production line wear. These innovations enhance the performance of ArcelorMittal Multi Part Integration (MPI) solutions, which streamline vehicle design by combining multiple vehicle components into a single Laser Welded Blank (LWB).


TRUMPF’s 3D laser cutting technology is capable of meeting the exacting tolerances required for ArcelorMittal’s Multi Part Integration (MPI) parts. These massive components are integral to the design of modern vehicles, where accuracy in shape and form is critical to ensure seamless integration and optimal performance.

By reducing material waste and optimizing production processes, TRUMPF’s laser technology not only streamlines manufacturing but also aligns with the industry’s growing demand for environmentally friendly practices. The non-contact nature of laser cutting ensures minimal wear on equipment, further enhancing the sustainability and efficiency of production lines.
