Introduction

CO2 lasers are versatile tools widely used in various industries for marking and engraving applications. Their effectiveness in marking metal surfaces relies on several key parameters and techniques. This article delves into the principles of CO2 laser technology, parameters influencing its efficacy, and its applications in metal marking, with emphasis on solutions provided by Huawo Laser Company.

Principle of CO2 Lasers

CO2 lasers operate by emitting infrared light at a wavelength of 10.6 micrometers. This light is generated through the excitation of carbon dioxide gas along with a mixture of nitrogen, hydrogen, and helium. The laser's ability to mark metal depends on its power density, absorption rate of the metal, and interaction time.

Parameters Affecting CO2 Laser Marking

Effective CO2 laser marking on metal is influenced by various parameters, including laser power, marking speed, focus position, and frequency. These parameters must be finely tuned to achieve optimal results.

• Laser Power: A higher power output, usually in the range of 30 to 100 watts, increases the marking depth and speed but might lead to overheating if not controlled properly.
• Marking Speed: Typically, marking speeds range from 100 to 300 mm/s. Higher speeds reduce the heat affected zone but may also decrease mark contrast.
• Focus Position: Precise focusing is crucial; an offset of around ±0.5 mm can lead to suboptimal results.
• Frequency: Operating frequencies between 5 kHz to 20 kHz allow for clean and efficient marking.
• Material Surface: Surface finish and reflectivity affect absorption rates. Pre-treatment might be necessary for highly reflective metals.

Applications in Metal Marking

CO2 lasers are used for marking various metals such as aluminum, stainless steel, and titanium. Applications include serial numbers, barcodes, logos, and compliance markings. The precision and non-contact nature of laser marking ensure minimal part deformation.
