What is a Fiber Laser Cleaner?

Laser cleaners use laser power to clean the surface of the material. Laser cleaning can be used to clean various materials, including ceramics, different metals, and alloys. A fiber laser system is the most efficient type of laser that uses a straight and smaller beam for focused cleaning.

It’s a non-contact cleaning method that does not involve any chemicals, abrasives, or mechanical force to remove the contaminants from the material surface.

A fiber laser amplifies the laser light within a special optical cable. The laser beam generated by a fiber optic cable is more focused and powerful with better control. Fiber laser cleaners are also advanced machines that are more energy-efficient and environmentally friendly than ordinary laser systems.

These high-tech machines can be fine-tuned to clean delicate surfaces with precision. Fiber laser cleaners are far more efficient and preferred in high-demand industries requiring accuracy and quality.

How Does a Fiber Laser Cleaner Work?

Fiber laser cleaner uses fiber laser technology to remove dust, debris, oil, rust, or other contaminants from the surface of the metal using the high-density laser beam.

Laser generation or beam delivery works like any other laser machine. A fiber laser generates the highly focused nanosecond-length pulses of the laser beam. The beam is transferred to the metal workpiece through an optic fiber cable.

The fiber laser control system controls the beam’s movement and intensity. It ensures the fiber laser position is accurate and focused on the workpiece.

When a laser beam strikes the metal surface, the energy is absorbed by the top layer. The substrate covering the metal or containments will turn into gas, or the pressure and heat will separate them from the metal surface.

Fiber laser cleaning is the most accurate, efficient, and easy way to clean metal of various densities. However, the correct laser setting is essential for precise laser cleaning results.

Laser beams can work on targeted areas and remove adhesive and glue stains from narrow, difficult-to-reach spaces.

5. Scale and Oxide removal

Scale is the deposit of minerals on a metal surface that can be difficult to remove if left for longer periods. Laser cleaners can remove oxidation marks, scale, and even heat discoloration from metal surfaces.

6. Welding Residues

Welding is the process of joining two metal pieces after melting them. It can leave marks on the sides and even scratches on the metal surface, which are easier to remove from the metal surface.

7. Dirt and Debris

Dirt and debris are commonly found on metal pieces. They can build up with time and get hard. The Laser cleaning process removes dust and debris from the metal surface.
