The train industry uses laser cleaning primarily as a decoating solution. Old train carriages need to be repainted once in a while, and especially very old carriages are finished with lead-paint or Cr6-components.
These paints are very toxic and should be handled with the greatest care. Laser cleaning offers a controlled solution for this problem, making it easier to get rid of the toxic dust and fume with a good vacuum system.
High Power systems can clean larger surfaces in a shorter timespan.
Multiple applications for laser cleaning can be found on shipyards.
A lot of surface cleaning applications need to be considered:
- Spot repair or spot preparation
- Weld or glue preparation
- Removal of light rust on uncoated areas
- Non Desructive Testing (NDT)
- Low Power series for small operations: spot repair, NDT, etc.
- High Power series for weld preparation, rust removal, etc.
The offshore industry is bound to follow very strict environmental regulations. If they want to clean or repair certain areas the traditional way, they need an encapsulation of the area, to make sure no cleaning waste (like sand or chemicals) can enter the water.
For this encapsulation, they often have to shutdown the complete system or the complete area, creating gigantic losses. Laser cleaning does not need an additive material for cleaning and can be used without any isolation.
