LASER MARKING
Annealing marking
When metal is heated, it is discoloured by an annealing effect. This happens because of structural changes
in the outer layer. A laser can be used to produce surfaces and structures of different colours
on the surface of the workpiece without employing any additives.
The table shows examples of different annealing colours of unalloyed steel.
The exact mechanical processing of ACSYS laser systems and focussing the laser
make it possible to position colours in the µ range.
Marked workpieces are temperature-stabile up to annealing temperature.
