Verified engineering data for Carbon Steel, Stainless Steel, Aluminum, and Brass across 1kW to 60kW power levels.
Fiber laser cutting performance depends on the balance of laser power density, assist gas purity/pressure, and nozzle orifice selection. For Carbon Steel (>12mm), High-Pressure Oxygen (O2 at 0.5ā1.2 bar) generates an exothermic reaction for clean vertical cut faces. For Stainless Steel and Aluminum, High-Pressure Nitrogen (N2 at 14ā22 bar) or High-Pressure Dry Air (16ā20 bar) prevents oxidation, yielding slag-free edges ready for direct robotic welding without secondary grinding.
