Frequently asked questions

Laser cleaning is a method where a concentrated laser beam removes unwanted layers from a surface without physical contact.

The laser energy is absorbed by rust, paint, soot, oil, oxides or other coatings. As these absorb the energy, the coating loosens or vaporises, while the material underneath remains as untouched as possible. The goal is to remove the contamination without damaging the base material.

This makes laser cleaning highly precise compared to mechanical methods such as grinding or sandblasting.

The technology can be used on both metal and several non-metallic materials, depending on choosing the right laser and settings.

The technology is used to remove, among other things, rust, oxides, paint, lacquer, grease, oil, soot, dirt, weld spatter, adhesive residue, coatings and corrosion.

• Gentle on the base material — the laser is set to mainly affect the coating being removed, not the material underneath.
• No chemicals — normally requires neither solvents nor strong chemicals, resulting in less waste.
• Dry process — no water or sand, meaning less mess and easier cleanup.
• Precision — well suited for machine parts, production equipment, moulds, welds and detailed components.
• Efficient — continuous fibre lasers can clean large industrial surfaces such as ships, pipes and structures quickly.
• Low wear — no brushes, abrasives or sand wearing down the surface.
• Can be done on site — handheld laser cleaners mean the work can be carried out at the customer’s location without disassembly or transport.

Laser cleaning generally produces less dust than sandblasting, avoids challenges related to chemicals, and can offer lower operating costs over time since the process uses no consumable materials.
