ABSTRACT:
In a method and an apparatus for depositing metal on a surface of an article, the surface of the article is heated to a state of incipient fusion. During the heating, a light beam is directed at the surface and the light reflectivity of the surface is detected. At the time of incipient fusion, an electrical control signal is created from the light reflections. Metal is deposited on the surface of the article after incipient fusion thereof and control of the deposit of the metal is effected in response to the electrical control signal.
