ABSTRACT:
A laser marking system for vitrification of a brick, tile, paver, or pot. A laser such as a continuous wave Nd:Yag or carbon dioxide unit is configured for optimized vitrescence of an object placed in the path of the beam. The beam is steered via computer controlled motors attached to reflecting mirrors located in the path of the beam. Graphical characters and letters can be vitrified into the surface of objects which are placed in the working area of the beam by running computer software for controlling the beam steering mirrors. A laser with adequate vitrification power will then vitrify, or change to glass, the surface of clay-containing objects falling in the path of the laser beam. The width of the beam, temperature and moisture content of the clay-containing object, gaseous atmosphere at the work surface and speed of beam movement can be optimized to maximize the throughput of a laser marking system. The laser marking system might also be mounted on a mobile unit for vitrification of already mounted bricks, pavers, or other such objects.
