For the processes of laser engraving and laser marking metals, the laser has been doing well for a long period of time. Using a laser marking machine, precise and clearly visible marking can be achieved on most metals from soft metals, such as aluminium to titanium or highly rigid alloys. With certain metals, such as steel alloys, it is likely to implement corrosion-resistant markings without damaging the surface structure by means of annealing marking. Laser marked products are marked with lasers in a diverse range of industries: These applications range from the marking of industrially produced series products for traceability to creating unique promotional items with logos or designs.
