Apparatus and method for soldering, fusing or brazing

摘要: A primary liquid having a boiling point at atmospheric pressure least equal to the temperature which soldering, fusing or brazing operation is be performed continuously boiled establish body of hot saturated vapor density greater than that air pressure. blanket secondary vapor, intermediate and atmosphere, floated on reduce losses thereof atmosphere. The article passed through into in vessel. Primary condenses article, latent heat vaporization condensing heating required for operation. After completion operation, withdrawn from blanketing out vessel atmosphere where it cooled ambient temperature.
