Fundamentals of Laser Marking
Created via Chat GPT, Edited by Bernard Martin
Laser marking is a process in which a laser beam is used to mark or engrave an object. The laser beam is directed at the surface of the object, and the energy from the beam causes a change in the surface material, resulting in a permanent mark.
There are several types of laser marking, including annealing, engraving, and foaming. The type of laser used, the material being marked, and the desired outcome will determine the specific process and technique used for laser marking.
Common materials that can be laser marked include metals, plastics, and ceramics. Laser marking is often used in industrial settings for product identification, traceability, and branding.
The term "laser" stands for "Light Amplification by Stimulated Emission of Radiation," which summarizes quite well exacty how lasers work. Light particles, called photons, are excited with an electrical current, causing them to emit energy in the form of light. This light forms the laser beam.
The principle of industrial traceability by laser engraving is based on a beam of high intensity laser focused and then directed towards the part to be marked. Its orientation is ensured by a galvanometric head composed of two mirrors. When a laser beam hits a part's surface, the energy is transferred in the form of heat, creating black, white, and sometimes colored marks.
In manufacturing, Lasers are a permanent, a precise and qualitative marking solution for part identification and traceability. Different applications may require different marking techniques such as engraving, staining, removing, annealing, and foaming are the most common marking methods. Each laser marking procedure will have its own unique advantages and disadvantages, depending on the materials being used and the quality requirement.
