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.

Apparatus for depositing metal on a surface of an article comprising,
- means for heating at least the surface of the article to a state of incipient fusion,
- means for directing a light beam at the surface during heating,
- means for detecting the light reflectively of the surface including reflectivity at the time of incipient fusion and for creating an electrical control signal from the light reflections from the surface at the time of incipient fusion of the surface,
- means for effecting deposit of the metal on the surface after incipient fusion thereof, and
- means for controlling the deposit of metal on the surface in response to said electrical control signal.
