FL-E200
The Pulse Laser Cleaning Machine is an advanced, non-contact cleaning solution designed for welded components maintenance. It efficiently removes weld oxide layers, slag, and surface contaminants without damaging the base metal, ensuring clean, high-quality welds suitable for further processing or inspection.
This technology is ideal for metal fabrication, shipbuilding, automotive, and industrial machinery, providing fast, precise, and eco-friendly cleaning.
Weld Oxide Removal
Effectively eliminates oxidation layers formed during welding, restoring the metal surface for subsequent coating, painting, or inspection.
Weld Slag Cleaning
Removes slag and spatter from welded joints without abrasive tools, maintaining surface integrity.
Non-Contact Cleaning
The pulsed laser cleans surfaces without mechanical contact, preventing scratches, deformation, or damage to the weld.
High Precision
Suitable for complex weld geometries and tight tolerances, ensuring uniform cleaning and surface quality.
Adjustable Parameters
Laser power, scanning speed, and pulse frequency can be customized for different metals, weld sizes, and contamination levels.
Eco-Friendly & Efficient
No chemicals or abrasives required, reducing secondary waste and environmental impact.
Welded Components: Steel plates, aluminum welds, stainless steel joints
Industries: Shipbuilding, automotive, metal fabrication, industrial machinery
Pre-Processing: Preparation for coating, painting, plating, or inspection
| Advantage | Description |
|---|---|
| Non-Contact | Prevents damage to welds and preserves base metal integrity |
| Chemical-Free | Environmentally safe; no solvents or abrasive media required |
| High Precision | Maintains weld geometry and surface quality |
| Adjustable Parameters | Laser power and scanning speed for different metals and weld sizes |
| Fast & Efficient | Suitable for single welds or batch processing |
| Minimal Waste | No sand, chemicals, or debris produced |
The pulsed laser emits high-energy light pulses onto the welded surface. The laser energy vaporizes or ablates weld oxides and slag while leaving the base metal intact. Adjustable parameters allow precise cleaning for various metals, weld thicknesses, and contamination levels.


Oxide Layer Removal: Effectively eliminates oxidation from metal surfaces, restoring the original metallic appearance.
Rust Removal: Safely removes rust stains without scratching or harming the substrate.
Oil & Grease Removal: Cleans oils, grease, and surface residues from manufacturing, handling, or processing.
Non-Contact Cleaning: Protects delicate or high-precision metal surfaces from mechanical damage.
High Precision & Adjustable Power: Laser parameters (power, frequency, scanning speed) can be fine-tuned for different metals and cleaning intensities.
Fast & Efficient: Suitable for both small parts and large surface areas.
