Precision Laser Cleaner for Welding Spot Preparation

Laser cleaning is a kind of green cleaning without any chemical or detergent, and the cleaned waste is basically solid powder, small in size, easy to store, recyclable, can easily solve the environmental pollution problems caused by chemical cleaning.

Overview


The Dedicated Laser Cleaning Machine for Welding Spots is a specialized solution engineered to enhance welding quality by removing contaminants from surfaces with precision and care. Using pulsed fiber laser technology, this machine safely eliminates oxidation, oil, grease, and other impurities from welding joints, ensuring strong, defect-free welds in critical applications where surface cleanliness is non-negotiable.


Features


Targeted Contamination Removal: 1064nm fiber laser with adjustable pulse width (10–200ns) and energy density (0.5–5J/cm²), focusing on 2–5mm wide weld seams while leaving surrounding areas untouched.

Vision-Guided Alignment: Integrated 2MP camera and laser positioning system achieve ±0.1mm accuracy, ensuring uniform cleaning along straight, curved, or complex weld paths.

Multi-Layer Cleaning Technology: Effectively removes three contamination layers—surface oils, intermediate oxides, and sub-surface impurities—improving weld penetration by 30% and reducing post-weld grinding.

Non-Abrasive Process: Preserves substrate mechanical properties (tensile strength, hardness) with no micro-scratches or material removal, ideal for delicate aluminum alloys and high-strength steels.

Automation-Ready Design: Standardized PLC interfaces (Ethernet/RS-485) and conveyor synchronization enable seamless integration into robotic welding lines, supporting speeds up to 1.5m/min.


Application


Critical for industries requiring high-integrity welds, this machine is used in:

Automotive Body-in-White: Preparing steel and aluminum alloy welding spots for car frames, improving joint corrosion resistance and structural strength.

Aerospace Welding: Cleaning titanium and Inconel surfaces before welding aircraft engine components and structural parts, meeting AS9100 aerospace quality standards.

Pipeline Construction: On-site cleaning of pipe welding joints in oil & gas projects, ensuring reliable connections in harsh environments with saltwater or high-temperature exposure.

Sheet Metal Fabrication: Removing protective coatings and rust from stainless steel sheets prior to robotic welding, reducing production delays and improving yield rates.


Why Choose Us


Welding-Specific Expertise: Developed in collaboration with leading OEMs, our cleaner is optimized for pre-weld surface preparation, reducing weld defects (porosity, lack of fusion) by 60%.

Process Efficiency: Cleans at speeds up to 10m²/h (heavy contamination), 40% faster than manual methods, with consistent results across large batches.

Compliance Assurance: Meets ISO 3834-2 welding quality requirements and is certified for use in IATF 16949 automotive and ISO 13485 medical device manufacturing environments.

Long-Term Reliability: Sealed laser head and industrial-grade components withstand high-dust, high-moisture welding environments, requiring only quarterly lens cleaning for maintenance.
