Laser cleaning and rust removal

All materials have characteristics that define their behaviour under specific conditions. Everyone knows about melting point, density, ductility, electrical conductivity. A less known characteristics of metal is their ablation thresholds.

When a laser beam is shone on a metal at intensity below its ablation threshold, the energy of the laser beam is dispersed as heat but it has no permanent effect on the metal. But if the intensity of the laser beam is above the ablation threshold, then some permanent change will affect the metal.

Rust, paint, varnishes and other contaminants all have ablation threshold below that of most metal.

A skilled operator is able to set the laser parameters so that the intensity of the laser beam is just above the ablation threshold of the contaminant but below that of the metal to be cleaned. Resulting in the removal of the contaminant without affecting the base metal in any way.

Several passes may be required, especially for thick layers of industrial paints. But the results are well worth the efforts.

Why use a laser for rust removal?

Fast and reliable technology

Laser allows the efficient and rapid cleaning and removal of rust on metal parts with various geometries.

Low maintenance, low consumables costs

Industrial laser systems are very low maintenance and have no consumable costs.

Enhanced versatility and productivity

Laser rust removal & cleaning systems are a very interesting alternative to hand or chemical cleaning methods. Cleaning trajectory can be easily and instantaneously changed through software.

Low energy consumption

New fiber laser based technologies offer low electrical consumption.

Laser rust removal

Rust is a substance formed by the corrosion of iron, it requires  the presence of oxygen and water. Rust is a slow oxidation which, with time, will damage the material. An incident high-power laser beam is quickly absorbed by the rust layer at the surface of a metal part. The rapid heating of the rust layer causes its melting and vaporization. With optimized process parameters, it is possible to remove the rust layer without damaging the underlying material.

Such a processes can be done in-situ with handheld laser cleaners such as Laserax's mobile laser cleaning system.
