Pulse Laser Cleaning Machine – Welding Joint Cleaning

Overview

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.


Key Features

  • 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.


Typical Applications

  • 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


Advantages

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

Working Principle

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.

Key Features

  • 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.


Applicable Materials

  • Carbon Steel

  • Stainless Steel

  • Aluminum

  • Copper

  • Titanium Alloy

  • Other common industrial metals


Advantages

Advantage Description
Non-Contact Avoids abrasion or deformation of the metal surface
Chemical-Free No acids, solvents, or cleaning agents required; eco-friendly
Precise & Controllable Can clean intricate or complex surfaces accurately
Wide Material Compatibility Works on steel, stainless steel, aluminum, copper, titanium, and more
Automation Ready Can be integrated into production lines or used as a handheld device
Minimal Secondary Waste No sand, grit, or abrasive residue generated

Typical Applications

  • Metal Fabrication & Surface Treatment: Sheets, pipes, rods, and profiles for coating, plating, or polishing preparation.

  • Industrial Maintenance: Gears, bearings, tools, and machinery parts restoration.

  • Automotive & Aerospace: Engine components, brackets, wheels, and structural parts.

  • Mold Cleaning: Tire molds, shoe molds, and injection molds, removing rubber residues, carbon deposits, and release agents.

  • Decorative Hardware & Jewelry: Zinc alloy, brass, copper, and stainless steel parts before polishing or coating.


Working Principle

The pulsed laser emits high-energy light pulses focused on the contaminated surface. The energy vaporizes or ablates rust, oxidation, and oil, leaving the base metal intact. Adjustable parameters allow precise cleaning for different materials and contamination levels.
