Operating Principle

How Laser Cleaning Works

Short nanosecond pulses provide high peak power and precise energy dosing.

1. Focusing

The 1064 nm beam is delivered through the optical fiber to the process head.

2. Pulse

A nanosecond pulse creates a high power density in the contamination layer.

3. Removal

Rust, oxide, paint, carbon deposits or another layer is heated/ablated and removed.

4. Clean Surface

With the correct process settings, the base material retains its geometry and is ready for the next operation.

Advantage of Pulsed Operation

High peak power with limited average thermal load makes the system especially suitable for applications where precision, repeatability and preservation of part geometry are important.

Applications

What the ROD 500 Bright+ Is Designed to Handle

The system is particularly suited to applications where the cost of surface damage is higher than the cost of cleaning itself.

1. Rust and Corrosion

Localized removal of corrosion products from metal; preparation for inspection, painting or repair.

2. Oxides and Scale

Removal of oxide layers; especially useful before welding, brazing and coating.

3. Paint and Coatings

Selective removal of paint/varnish in the work area without abrasive blasting contamination.

4. Oil and Contamination

Removal of process contamination and surface preparation for bonding/coating.

5. Molds and Press Tooling

Removal of rubber, polymer residues and deposits while preserving surface geometry.

6. Weld Areas

Cleaning before and after welding; localized removal of contamination and oxides.

Where the System Delivers the Greatest Value

On complex-shaped parts, molds, mating surfaces, weld areas and high-value components where repeatability, abrasive-free processing, localized treatment and geometry preservation are critical.

Industries

Metalworking, Power Generation and Service

The ROD 500 Bright+ is particularly effective for localized, precise and repeatable cleaning.

1. Metalworking

Preparation for welding and painting, oxide removal, and cleaning of parts and production tooling.

2. Oil & Gas Service

Localized corrosion, flange areas, pump/valve components, threaded and mating surfaces, subject to testing on the specific part.

3. Power Generation and Repair

Cleaning of critical parts, assemblies, rotors/stators and NDT inspection areas without abrasive contamination.

4. Transport and Rail

Repair areas, localized coating removal, and cleaning of welded joints and components.

5. Aviation and Precision Manufacturing

Surfaces where controlled energy input, geometry preservation and process repeatability are important.

6. Restoration and Stone

According to NARRAN, the technology is also used on stone/masonry to remove soot, contamination and certain coatings.

Practical Selection Principle

The more valuable the part, the more complex its geometry, and the higher the cost of damage/disassembly, the stronger the economic case for pulsed laser cleaning. For thick layers over large areas, productivity should always be confirmed by testing.

Integration

From Manual Operation to a Robotic Cell

One laser source can serve as a maintenance tool or as part of an automated process.

Manual Operation

The operator uses the process head directly on the part. The 10-meter fiber provides a wide working radius without constantly moving the main unit.

Automation

According to NARRAN, the head can be integrated into an industrial line; the current platform supports interaction with industrial systems and robots.

Process Economics

Process economics are determined by more than cleaning speed.

No Abrasives	No need to purchase or dispose of sand/blasting media.
No Chemicals	No solvent required.
Less Disassembly	Cleaning can be performed directly at the equipment.
Repeatability	Saved settings reduce variation in results.

Business Value

Why the ROD 500 Bright+ Is More Than Just a Cleaner

It is a tool for reducing the risk of part damage and standardizing the cleaning process.

1. Surface Preservation

There is no mechanical contact with the surface. This is an important advantage for molds, mating areas and precision parts.

2. Process Control

Adjustable power, scan width and scan shape allow the process to be tuned to a specific layer.

3. Mobility

A wheeled enclosure plus long optical fiber allow one system to be used in different work areas.

4. Service Life

The stated diode lifetime of more than 100,000 hours reduces long-term total cost of ownership.

5. Flexibility

From manual cleaning to line integration – one technology platform.

6. Image and Standardization

A Czech industrial system based on fiber technology, with clear documentation and industrial controls.

The ROD 500 Bright+ Advantage

For regular abrasive-free cleaning of high-value surfaces, fast changeovers and repeatable results, the 500 W pulsed system becomes a production tool rather than a service device.

Key Figures

For an accurate assessment of cleaning speed and quality, evaluation of the actual surface, contamination type and required result is recommended. Testing is what turns a versatile laser into a predictable production process.

Application Areas and Technological Capabilities

The laser cleaning system is intended for industrial use at manufacturing, power generation, engineering and repair facilities where regular equipment maintenance, restoration of high-value assemblies and components, localized surface preparation or cleaning before subsequent process operations is required. The technology is particularly effective where controlled removal of light to moderate corrosion, oxide layers, carbon deposits, oils, process contamination, paint and other coatings is required without abrasive materials and with minimal impact on the base material. Pulsed laser cleaning is especially valuable for applications where precision, repeatability, preservation of part geometry, localized treatment and the absence of secondary abrasive contamination are important.

Technological Advantages

Depending on the specific application, laser cleaning can provide:

• Non-contact surface treatment.
• No sand, shot or other abrasive consumables.
• Minimal secondary waste.
• Localized treatment of only the required area.
• Automation and integration into production lines.
• High process repeatability.
• Cleaning of complex-geometry parts.
• Surface preparation immediately before welding, inspection, coating or restoration.

In many cases, an assembly can be treated without complete equipment disassembly, provided there is safe optical access to the surface being cleaned and laser-safety requirements are observed.

Industrial Tool Applications

The laser system should be considered not as a specialized device solely for rust removal, but as an industrial tool for:

• Maintenance and repair.
• Surface preparation.
• Non-destructive testing.
• Restoration of high-value components.
• Cleaning precision tooling.
• Cleaning molds.
• Preparation before welding and coating.
• Localized cleaning of critical metal surfaces.

The technology delivers the greatest economic benefit where the value of the part, tooling or equipment is significantly higher than the cost of the cleaning operation and where preserving the geometry and condition of the base surface is critically important.

Technology Limitations

Pulsed laser cleaning is not a complete replacement for abrasive blasting. For large areas, structures with severe deep corrosion, thick rust layers or heavy coatings, abrasive blasting, shot blasting or another high-productivity technology is often more appropriate and cost-effective.

Laser Technology Is Most Effective For:

• Light to moderate corrosion.
• Localized cleaning.
• Work on high-value and precision components.
• Surface preparation before non-destructive testing.
• Cleaning molds and tooling.
• Removing coatings and contamination where abrasives are undesirable or unacceptable.

For parts made of heat-resistant alloys, components with functional coatings, claddings, thermal-barrier coatings, hardened layers or other special surfaces, process parameters must be selected individually. Before industrial implementation, the base material, type of contamination or coating, and acceptable surface condition after treatment must be defined. Thus, the primary value of pulsed laser cleaning lies not in maximum material-removal speed, but in process control, selectivity, repeatability and the ability to perform high-precision cleaning where traditional abrasive methods may be undesirable or technologically unacceptable.
