Laser Cleaning Applications

Laser cladding is an effective way to clean & repair high value parts such as turbine engines and automobile engines that can be damaged due to their high operational temperatures and exposure to abrasive particulates. Laser cleaning removes impurities, oxides, dust, oil or other materials. The laser beam is pulsed at the surface of a material, irradiating and vaporizing the layer until the desired depth of ablation has been reached. 

Outdoor stonework and headstones are very prone to “wear and tear” caused by ageing especially due to environmental hazards and conditions. It can often be challenging, costly and impractical to clean these precious works of arts with traditional methods. 

 

Thanks to lasers though there is a relatively new method of cleaning stonework, statues and monuments--with no harm or damage to the artifact or stonework.

Simply this is the preparation of a surface through a treatment—virtually always to increase the adhesion capability of coatings.
Industry professionals say that the most important factor, which influences the long-term performance of coatings is the quality with which the surface had been prepared.

 

Traditionally this was achieved chemically or mechanically, but a modern-day emerging approach is to treat surfaces with laser technology.A laser beam is pulsed at the surface of a material, irradiating and vaporising the layer until the desired depth of ablation has been reached. 

For classic car restoration and paint preparation the laser cleaning increases the adhesion capability of coatings--that the most important factor, which influences the long-term performance of coatings is the quality with which the surface had been prepared.

This cleaning process can be used to remove graffiti paint from almost any surface, either partially, fully, or on a selective area, whether the surface has been finished with an organic, chemically oxidized or anodized surface. 

 

The layer that you are removing will be different to that of the object underneath, both physically and chemically, meaning that the laser will have no thermal, chemical or mechanical effect on the substrate itself.

Application examples include the cleaning of print rolls and mould tools.

 

We have a technique for large area processing due to the higher efficiency of wider, even, high frequency fill pattern overlapping.

 

Lasers with Gaussian energy distributions can cause substrate damage due to the high peak powers in the centre point of the beam and need higher overlaps reducing processing efficiencies.
