Abstract
Wave soldering is accomplished in an enclosure having an atmosphere which is substantially free of oxygen and which provides a fluxing action due to the presence of a gaseous reducing agent. A conveyor carries articles to be soldered through the enclosure by means of an entrance and exit which are provided with gas curtains to inhibit atmosphere exchange with the ambient air.
