In the field of industrial surface cleaning, traditional rust removal methods such as chemical treatment and sandblasting often suffer from low efficiency, environmental pollution, and potential damage to the base material. Foster Laser's fiber laser cleaning technology offers a revolutionary alternative — delivering high efficiency, environmental friendliness, and precision with no damage to the substrate. It is rapidly becoming the preferred solution for laser rust removal on metal surfaces.
Based on over a decade of field experience, Foster Laser has developed a practical and easy-to-learn “Observe + Evaluate + Calibrate” three-step tuning method. Whether you're a novice or an experienced technician, this guide will help you weld with professional-grade precision and consistency.

How It Works: Cleaning with Light, Restoring with Precision
Foster’s laser cleaning machine uses high-energy-density infrared laser beams, which are focused into powerful pulses directed at rusted metal surfaces. The rust layer instantly absorbs the laser energy, converting it into intense heat. This rapid thermal expansion breaks the adhesion between the rust particles and the metal substrate, enabling the rust to be removed instantly and efficiently.
This non-contact, consumable-free process ensures precise depth control, leaving the base material intact and restoring the surface to a bright, mirror-like finish.

Five Stages to Complete Rust Removal
✨Laser Emission & Focusing
High-energy laser beams are emitted and precisely focused through an optical system onto the rusted areas for targeted treatment.
✨Energy Absorption & Localized Heating
The rust layer rapidly absorbs the concentrated laser energy, reaching temperatures of several hundred degrees within milliseconds.
✨Plasma Formation & Shockwave Generation
The extreme heat causes the formation of plasma, whose rapid expansion generates powerful shockwaves that break apart the rust structure.
✨Particle & Impurity Removal
The resulting shockwaves eject gas, dust, and rust fragments from the metal surface, leaving it clean and residue-free.
✨Smart Control for Base Protection
Intelligent systems adjust the laser’s power and scanning range in real time, ensuring that only the rust is removed — with zero damage to the underlying metal.
If you detect anomalies, don’t panic. Start by wiping the protective lens gently using lens tissue—most issues stem from splatter or dust. If the problem persists, it’s likely due to optical misalignment. In this case, contact the Foster pulse Laser cleaning machine support team for guided remote calibration of the reflective mirrors.
