  • How Does Laser Cutting Work? - ESAB Welding & Cutting

    When cutting mild steel, the heat of the laser beam is enough to start a typical “oxy-fuel” burning process, and the laser cutting gas will be pure oxygen, just like an oxy-fuel torch. When cutting stainless steel or aluminum, the laser beam simply melts the material, and high pressure nitrogen is used to blow the molten metal out of the kerf.


    9. Be skeptical of claims made by proprietary fuel gas suppliers for hotter flame temperature, faster cutting speed or better cut quality. Cutting speed on a thin plate (less than or equal to 1/2”) is controlled by preheat intensity (flame temperature) and in heavier plate cutting by oxygen stream shape and quality, not the fuel type.
