Introduction to CO2 Laser Marking

CO2 lasers, known for their efficiency in industrial applications, utilize carbon dioxide gas mixed with other gases to produce a laser beam. Their ability to mark a wide range of materials makes them a popular choice in manufacturing.

Mechanism of CO2 Laser in Metal Marking

CO2 lasers operate on a wavelength of 10.6 micrometers, making them well-suited for non-metallic surfaces and some treated metals. The marking process involves the laser beam vaporizing the material surface, creating a contrast with the surrounding areas.

Factors Influencing CO2 Laser Marking

Several factors affect the efficiency and quality of CO2 laser marking on metals:

• Material Composition: Metals with coatings or treatments such as anodized aluminum respond better to CO2 lasers.
• Power Level: A power output ranging from 25 to 100 watts is typical for marking metals effectively.
• Beam Focus: A smaller focal spot size results in finer detail in the marking process.
• Marking Speed: Speeds between 100 to 500 mm/s are recommended to balance between clarity and time efficiency.

Technical Parameters for Effective Marking

Optimizing technical parameters is crucial for achieving precise and lasting markings:

• Laser Frequency: Frequency settings of 20 kHz to 30 kHz are frequently used for metals.
• Pulse Duration: Shorter pulse durations lead to finer marks, typically in the range of 5 ms to 20 ms.
• Marking Depth: Depths of 0.1 mm to 0.3 mm are optimal for legibility and durability.
