LASER CUTTING

CO2 Laser vs Fiber Laser



A question frequently asked in the plate laser cutting industry, mostly by customers, is what the difference is between a fiber laser and a CO2 laser.

A fiber laser, suitable for the cutting of metals, coated metals and plastics, amplifies a laser beam that is generated by diodes in energy supplied glass fibers.The laser beam will then befocused through a lens cutting the sheet metal. On the other hand CO2 lasers generates a laser beam through electricalstimulated carbon dioxide gas mixture pushed through a tube with optical mirrors. CO2 lasers are mainly used for cutting wood, glass, paper, etc. CO2 lasers compared to fiber lasers have better cutting quality and speed when cutting thicker materials.

Choosing the alser cutting technique which will give you the best quality sheet metal components, your first step will be to look at the type of material and the thickness.

Advantages of Fiber Lasers and CO2 Lasers:

Fiber Laser CO2 Laser
High beam quality (single mode beam quality) Very good beam quality
High processing speed Average at 250 watt of power
Ideal for scanner welding Faster straight line cut
For applications where a narrow weld seam is required Thicker material has a smooth surface finish
First choice for precision application First choice for thick material


Advantages of a fiber laser over CO2 laser:

  • There is no moving parts during the cutting of sheet metal components.
  • The operating costs are lower than that of the CO2 lasers, while the maintenance is also a lot less.
  • When comparing a fiber laser with a CO2 laser in terms of power, the fiber laser is one step ahead.
  • The speed of a fiber laser is higher when laser cutting sheet metal components out of thin material.
  • The fiber laser's speed is 3 times faster than the CO2 laser when cutting 1mm mild steel, galvanised or stainless steel sheet metal components.
  • There is no need to worry about any back reflections during the cutting of reflective materials.
  • The service cost is around 50% lower than a CO2 laser's service.
