(2) Typical Process Flow

Laser Cutting: Fiber laser cutting (6kW power) achieves 0.5mm narrow-seam cutting

Preforming: Rough forming via three-roll bending machine, controlling curvature radius at 120% of design value

Finishing Forming: Final shaping using hydraulic press with contouring dies, holding pressure ≥30s

Post-Processing: Shot peening (coverage 200%) to eliminate residual stresses
