ABSTRACT:
This disclosure is directed to the vapor condensation heating of articles to an elevated temperature so as to perform, for example, a soldering, brazing or fusing operation thereon, without requiring the immersion of the articles within the heat transfer liquid-generated body of hot saturated vapor. This is accomplished in accordance with several methods and apparatus which allow the saturated body of vapor to controllably rise to and heat only a selected underside surface area (or areas) of each article, in succession, while minimizing the loss of any vapor to the atmosphere at all times.
