White Engravings

In this very fast process, the surface of the material is slightly melted, creating a white or light contrast. The absorbed intensity lies between the melting and vaporization thresholds of the alloy. In white engraving, the thermal penetration depth in the material is usually less than 5 µm, which is particularly advantageous for corrosion-prone or coated components. This smoke-free process leaves a subtle inscription and is therefore especially suitable for darker surfaces. Logos are also frequently applied using white engraving. Additionally, this method is often used in combination with black engraving to both remove the smoke and deposits from the black engraving and to enhance the readability of codes or inscriptions.
