Robotically-driven laser ablation workhead stripping top coatings from an H-53 helicopter glass-fiber composite rotor blade

World’s only laser ablation system in production use on flight-critical surfaces 

Lasertronics has developed unique scanning and computerized control technologies that for the first time make laser ablation a practical alternative to blasting, abrasives, and solvents for removing coatings of any kind, with no risk of damage to any substrate.

Our pulse-by-pulse closed-loop control enables fast and thorough stripping of coatings, using powerful off-the-shelf industrial lasers. Our color-selective workhead allows stripping directly to the substrate or to intermediate layers.

Benefits of Lasertronics’ Unique Ablation System

  • Safe for Any Substrate: Absolutely safe for any substrate – no risk of damage as with scraping, sanding, solvents, or media blast. No risk of overheating substrate as with open-loop lasers.
  • Complete: Cleans any visible surface, regardless of complexity, with zero residue.
  • Unprecedented Control: Selectively removes specific layers from multi-layer coatings, leaving the rest undisturbed.
  • Fast: Replaces manual labor with 10X faster process.
  • Savings: Significant reduction in labor, out-of-service time, and disposal costs.
  • Easy Access: Flexible work head allows easy access to cramped spaces. Optional video camera enables remote use in inaccessible or dangerous areas.
  • Reduce Injuries: Eliminates repetitive-stress manual labor.
  • Portable and Flexible: Small, light-weight, portable unit runs on standard shop power.
  • Adaptable: System accommodates manual or robotic applications.
  • Green: Allows capture of stripped toxic and radioactive material in HEPA paper filter for easy control and inexpensive disposal, keeping it out of air and water.
  • Clean: Reduces waste stream to 1% of the volume generated by conventional stripping techniques.

Applications

  • Aircraft Maintenance – Fixed Wing & Rotary: Strip corrosion, paints and sealants; repair multi-layer surfaces including low observables.
  • Ship Maintenance – Surface & Submarine: Strip corrosion, paints and adhesives from any surface; prepare weldments for NDI.
  • Composite Manufacturing: Prepare composite surfaces to accept coatings without use of abrasives, peel-ply or solvents.
  • Radioactive Decontamination: Decontaminate to free release.

Awards

  • US FAA Endorsement
