ArcelorMittal has chosen a partner to develop new welding technologies

ArcelorMittal has teamed up with leading welding system manufacturer ANDRITZ Soutec, promoting cutting-edge laser welding technology around the world. ArcelorMittal has developed the patented Usibor laser ablation technology for welding hot stamping steel. The partnership with ANDRITZ Soutec will enhance this technology and make laser welding more affordable for tough steels, which is becoming highly sought after by automakers as they strive to make cars light, economical and safe.

ArcelorMittal is a leading supplier of coated steel using zinc plating and hot stamping. The company has developed advanced hot stamping products, Usibor and Ductibor, with a coating that protects vehicle parts during heat treatment and prevents corrosion. However, without the laser ablation process, the weld can become brittle and corrosive. Laser ablation removes an aluminum-silicon coating from the surface near the weld, which is evaporated, and then laser welding is carried out.

Laser welded blanks allow automakers to reduce vehicle weight and improve safety, while hot stamping steels are the best way to increase strength with thin and lightweight parts.

Philippe Baudon, CEO of ArcelorMittal, Tailored Blanks, said that "By working with welding technology leader ANDRITZ Soutec, we are taking a new stage in the development of cost-effective solutions, supporting car manufacturers to reduce vehicle weight and improve crashworthiness." Thanks to this cooperation, effective solutions will be offered to the global automotive industry to reduce carbon dioxide emissions into the atmosphere.
