Introduction to Fiber Laser Technology
LaserMaster™ Fiber laser systems have revolutionised industrial processes, particularly in cutting and welding applications. These powerful tools rely on focused light emitted through fibre optic cables to perform precise and efficient operations. The key to maximising their effectiveness lies in selecting the right Fibre-laser system and the auxiliary gases used during operation.
Basically what is needed is a Compressed Air with Refrigerated Air Dryer. This is to Protect the Fibre Laser Lens; it should have a flow rate of 40L/m, 4 Bar Pressure, as it needs a Cold, Dried and Cleaned Air Source.
Understanding Auxiliary Gases in Fiber Lasers
The Impact of Gas Purity
Oxygen and Nitrogen in Laser Cutting:
Different gases are used depending on the material in laser cutting — oxygen aids in the combustion and removal of molten material, especially in cutting low-carbon steel plates. For stainless steel and aluminium alloys, nitrogen is preferred to prevent oxidation and ensure a clean cut. The purity of these gases significantly affects the cutting quality, with impurities like water impacting the cutting surface’s appearance and quality.
Why Gas Purity Matters
Protecting the Laser Lens:
Impurities in auxiliary gases can lead to fluctuations in cutting power and inconsistencies on the cutting surface. Moreover, these impurities can harm the laser lens, affecting the overall efficiency and lifespan of the tool and its respective parts.
The Necessity of Cold, Dried, and Cleaned Air
Maintaining Laser Efficiency
For optimal performance, fibre lasers require air that is not only dry and clean but also cold. This specification ensures that the air doesn’t introduce contaminants that could degrade the lens or the laser’s cutting ability.
Alternatives to Compressed Air
Bottled Compressed Air and Nitrogen Cylinders
Bottled compressed air or nitrogen cylinders are excellent alternatives when compressed air isn’t available. These options offer the needed purity and can be more convenient in specific operational settings.
Specific Requirements for Laser Operations
Tailoring Gas Use to the Application
Flow Rate and Pressure Needs:
Compressed Air with Refrigerated Air Dryer is Needed at a specific Flow-rate of 40L/m Dew Point <3°C, 4 Bar Pressure in a cold, dried and cleaned/ purified air source
Welding Applications:
In welding, different gases might be used, such as specialised welding gases, which are also typically supplied in cylinders. These gases are chosen based on their properties that complement the welding process.
Advancements in Fiber Laser Technology
Innovations Enhancing Performance
Recent advancements in fibre laser technology have led to increased output power and efficiency. Various fibre lasers, such as high-power, narrow linewidth, and upconversion fibre lasers, have applications in diverse industries, ranging from telecommunications to medicine
Conclusion
Using cold, dried, and cleaned air in fibre-laser tools is not just a recommendation but a necessity for maintaining the quality and longevity of these advanced devices. Understanding the role of auxiliary gases and adhering to specific requirements ensures that fibre lasers operate at their highest potential, providing precision and efficiency in industrial applications.
