Laser Engraving & Marking: Applications & The Scope of the Invention
It is a well known fact that laser marking, engraving and etching are a permanent process that is carried out by the beam of a concentrated laser to produce a permanent marking on the surface of a suitable material. While this process encompasses quite a wide range of applications, it is nevertheless a remarkable invention as well. Laser marking, can be executed with a relatively low powered laser device. Because of the reason that the beam is of low power, it does not increase the temperature of the metal surface as in the case of the other marking and engraving techniques that were being done previously, which would produce a rise in temperature of the material surface as well as the device head. The main methods that make use of the laser techniques are laser marking, laser engraving and laser etching. These are further categorised based on the power, substrate and so on. Laser marking is split down into annealing; foaming and carbon migration. Since laser engrav...
