Fiber laser systems for metal cutting: a short overview

The process of precise metal cutting by hand is considered to be very challenging that is why the need for safer, quicker, and easier technology increases. Fiber laser technology is perfect for cutting because it focuses on laser beams of light to cut different materials, especially metals that are difficult to process compared to standard ones such as wood, acrylic, and MDF.
To be more precise, numerous types of laser system cutters are distinguished, however, CO2 and fiber laser cutters are regarded as the most popular. The thing is that these systems are very different from one another, herewith, they can be dangerous if applied improperly.
It should be noted that CO2 laser systems use oxygen assistance to cut metal. Safety rules are highly important here because these laser systems can provoke lacerations, burns, and immediate blindness, as well as combustion or explosion (because of oxygen) when employed improperly.
Fiber lasers, in turn, have a higher level of power, therefore, they also have similar consequences when used improperly. It is very important to wear safety equipment? for example, safety glasses and gloves when working with fiber lasers and apply the appropriate laser beam coatings.
Additionally, the application of fiber laser systems requires a well-ventilated room because some laser systems can emit noxious or even toxic fumes. There is an opinion that laser beam cutting is a challenging task since some metals are difficult to cut because of their properties (density, reflectivity, and the way they absorb heat).
Sometimes the cost of CO2 laser systems is cheaper, but they always need oxygen and are limited to cutting less-reflective metals, while fiber lasers do not require any additional components but their cost is typically higher. Thus, the cost of both types limits the metal cutting to professional and industrial applications.
Experts offer several pieces of advice to make the laser beam cutting process easier and faster and get the best results. Herewith, it is necessary to pay careful attention to various materials processed by CO2 or fiber laser systems. The advice is the following:

  • Elevate the material by a platform raised on spikes in order to decrease the heat dissipation.
  • Conduct tests in order to save a lot of future hassle.
  • Separate gas from the laser system if oxygen or nitrogen is used for safety. 
  • Make good cuts.
