As manufacturers continuously improve production efficiency and surface treatment quality, traditional cleaning methods are increasingly challenged by numerous problems, such as abrasive consumption, chemical waste, dust generation, and inconsistent cleaning results.

Composite laser cleaning technology offers a modern alternative for industrial surface treatment. By combining the power of continuous wave lasers with the precision of pulsed lasers, composite laser cleaning machines can handle a wider range of contaminants and metal surface conditions than single laser cleaning systems.

Advantages of Composite Laser Cleaning

The advantage of composite laser cleaning lies in the simultaneous functional combination of continuous and pulsed lasers, creating a synergistic effect where 1+1>2. Its principle primarily utilizes the continuous laser as a heat conduction output, causing the deposits to absorb energy, generating vaporization and plasma clouds. This creates thermal expansion pressure between the metal material and the deposits, reducing the interlayer adhesion. When a pulsed laser outputs a high-energy pulsed laser beam, the resulting vibrational shock wave causes the adhered substances to detach directly from the metal surface, thus achieving rapid laser cleaning.

Composite Laser Cleaning Applications

Laser composite cleaning can be applied to cleaning thick coatings and strongly adhered substances. It can remove resin, paint, oil, stains, dirt, rust, coatings, plating, and oxide layers from object surfaces. Its applications are wide-ranging, covering shipbuilding, automotive repair, rubber molds, high-end machine tools, railways, and environmental protection.

Composite Laser Cleaning Application Case

Railway wheelsets accumulate rust, paint, grease, and surface contaminants during operation and maintenance.

Due to the large cleaning area and the requirement for minimal surface damage, composite laser cleaning systems can serve as a highly efficient surface treatment method.

Composite Laser Cleaning vs. Conventional Surface Treatment

Different industrial cleaning technologies have different strengths. The right choice depends on the workpiece, contamination, production volume, and required surface quality.

How to Choose a Composite Laser Cleaning Machine

Choosing the right composite laser cleaning machine involves considering the following factors:

• Workpiece material
• Type of contamination
• Cleaning area and efficiency
• Required cleaning quality
• Manual or automatic operation

SDQY LASER's Composite Laser Cleaning Solutions

SDQY LASER is dedicated to developing laser cleaning equipment for industrial surface treatment.

Our composite laser cleaning solutions can be configured with different combinations of continuous wave and pulsed laser sources to meet application requirements, such as 2000W continuous wave + 500W pulsed and 3000W continuous wave + 500W pulsed configurations.

Because the material properties and contamination levels of each workpiece are different, sample testing is crucial before finalizing the machine configuration.

SDQY LASER can perform sample testing based on your specific application and recommend the appropriate laser power and configuration.
