ABSTRACT:
A heat transfer liquid having a boiling point at atmospheric pressure at least equal to the temperature at which a soldering, fusing or brazing operation is to be performed, is floated on a pool of a liquifiable metal having a density greater than, a melting point below, and a heat of vaporization above, that of the liquid. The metal is heated to a temperature between its melting and boiling points, and at least to the boiling point of the liquid, to continuously boil the liquid to establish a body of hot, saturated vapor having a density greater than that of air at atmospheric pressure. An article on which the soldering, fusing or brazing operation is to be performed is extended into the body of vapor to condense the vapor thereon. The latent heat of vaporization of the condensing vapor heats the article to the temperature for the operation, and the article is then withdrawn from the vapor for cooling.
