Laser Welding Dual Door Ring

Reduce body shop complexity and lower investment in stamping dies
· Highly integrated, one-piece design to minimize assembly process costs
· Customized optimization of material properties and efficient load transfer
· Lighter vehicle body with reduced steel consumption
· Integrated material optimization, resulting in fewer stamping dies and weld points
· Compliance with 2025 side-impact regulations; enhanced rear-impact performance for the entire vehicle

Soft Zone

· Circulate cooling water in areas requiring higher strength to ensure a sufficient cooling rate, thereby achieving a fully martensitic transformation;
· Heat the die in areas requiring higher ductility to reduce the cooling rate, resulting in a mixed microstructure—comprising martensite, bainite, and ferrite/pearlite—to create zones with varying degrees of hardness and softness within the part;
· Enable the tailored configuration of a component's strength, hardness, and other properties, ultimately enhancing the vehicle's overall crash performance.

R/FLR&S/MBR

· Lightweighting: 3.0 kg weight reduction (a 17.1% decrease)
· Crash performance: Enhanced vehicle structural rigidity
· Corrosion resistance: Improved sealing and anti-corrosion performance
· Superior assembly tolerance precision
· Reduced carbon footprint for the vehicle underbody
