Laser Ablation Process

ArcelorMittal's laser ablation system expands the ability to use high strength steel in automotive applications. This enables making laser-welded tailored blanks using multiple steel gauges. In turn, Magna-Cosma reengineered their tooling to allow hot-stamping blanks comprised of multiple gauges, so that the door ring on the Acura MDX can be hot-stamped as a single piece. This significantly enhances the strength of the passenger compartment, improving crash performance while reducing weight for improved fuel economy.
