Abstract

See full text

The present invention resides in a method of providing a mark on a surface of a metal component, where the mark comprises a symbol (301) representing a first entity of information and the method comprises a step of laser marking, in which a controllable laser beam is used to form the symbol (301) from two or more separate line segments (33 1-334), each line segment (33 1.334) having at least one point of overlap with another line segment. According to the invention, the method further comprises a step of embedding a second entity of information within the mark by modifying a sequence in which the two or more separate line segments (33 1-334) are formed.
