What surface cleanliness standards can laser preparation achieve?

Laser surface preparation can achieve Sa 2.5 (near white metal) and Sa 3 (white metal) cleanliness standards as defined by ISO 8501-1, as well as specific surface roughness profiles (Ra/Rz) for coating adhesion.

Is laser surface preparation suitable for pre-weld cleaning?

Yes. Laser cleaning is highly effective for pre-weld preparation, removing oxides, coatings and contaminants from the weld zone without introducing abrasive contamination that could affect weld quality.

Can laser preparation replace abrasive blasting?

In many applications, yes. Laser preparation offers greater consistency, no media contamination, no chemical residue and is suitable for complex geometries where blasting is impractical. For large open surfaces, blasting may still be more economical.

Can you achieve specific surface roughness values?

Yes. Our laser systems can be tuned to achieve specific Ra and Rz roughness values, which is important for optimising adhesion in high-performance coating systems.

Laser Surface Preparation for Coating & Welding

Achieve adhesion profiles and cleanliness standards impossible with traditional methods — without abrasives, chemicals or substrate damage.

The quality of any coating, weld or bond is only as good as the surface preparation beneath it. Laser surface preparation delivers cleanliness levels and adhesion profiles that exceed what abrasive blasting and chemical treatment can achieve — consistently, repeatably and without damaging the substrate.

How It Works

The Laser Cleaning Process

Our pulsed fibre laser removes contaminants, oxides and existing coatings from the surface, creating a clean, activated substrate with a controlled surface profile. The laser can be tuned to achieve specific roughness values (Ra/Rz) that optimise adhesion for the intended coating system. The process is repeatable and fully controllable — unlike abrasive blasting, which varies with media condition, pressure and operator technique.

"I recently had an old dumbbell set restored by Lightwork after it had been sitting in my garden for years and had become heavily rusted. They used laser cleaning to remove all the rust without damaging the metal, and the weights now look fantastic. The whole process was professional from start to finish. They turned up when they said they would, explained what they were doing, and the quality of the finish exceeded my expectations. It's saved me from having to replace the whole set. I'd happily recommend them to anyone looking for rust removal or laser cleaning services. Great workmanship and excellent service."
