Introduction

The use of CO2 lasers in marking metal surfaces has become increasingly popular in various industries due to its precision and efficiency. This article delves into the mechanisms of CO2 laser marking, discussing the specific parameters required for effective marking and highlighting solutions provided by Huawo Laser Company.

Principle of CO2 Laser Marking

CO2 lasers operate at a wavelength of 10.6 μm and are primarily used on non-metal and some metal surfaces. The mechanism involves using the laser to generate heat at the surface, which causes a change in the material’s surface that is visible to the human eye. This process may involve either engraving or annealing, where the laser energy is absorbed by the metal, causing oxidation or color change.

Parameters in CO2 Laser Marking

The effectiveness of CO2 laser marking on metal surfaces depends on controlling several key parameters:

• Power Output: Typically ranges from 10W to 400W. Higher power outputs increase the marking speed but may affect precision.
• Scan Speed: Generally between 100 mm/s and 7000 mm/s. Faster speeds enable quicker processing times.
• Frequency: Varies from 1 kHz to 100 kHz. Influences the pulse duration and intensity.
• Focus Lens Distance: Affects the accuracy and quality of the mark, usually kept between 50 mm to 300 mm depending on the desired resolution.

Applications and Benefits

CO2 laser marking is used in various applications including automotive part manufacturing, electronic components, and medical devices. The benefits of using CO2 laser marking include precision, non-contact processing, and minimal thermal distortion, making it ideal for delicate components.
