Laser Marking of Stainless Steel
Laser Marking on stainless steel with a CO2 laser is very timely and messy process. Due to the reflective nature of the metal surface and the operational wavelength, CO2 laser systems require a laser marking material (LMM, such as Thermark or Cermark) to permantly mark the surface. The LMM is sprayed onto the surface and has to be allowed to dry before marking. The surface also has to be cleaned after marking. All of this work makes the alternative, Fiber Lasers, very appealing.
Q-Switched Fiber Lasers are ideal for marking on stainless steel and other metals, as no LMM is needed. Stainless steel parts are marked using the process of surface etching. This is to create an etch mark by vaporizing the surface of the material at very high speeds, providing very minimal damage to the part. This is usually done when a quick mark is needed and cycle time is an issue. A surface etch gives a high contrasting mark and is ideal for marking on coatings without penetrating through, such as Chrome, Nickel, etc.
