ABSTRACT:
A method and device for joining work pieces by soldering or brazing is disclosed whereby an induction coil is brought to a position where it at least partly surrounds the work pieces which by induction are heated to a suitable temperature for effecting the soldering or brazing operation after which solder is fed to the soldering or brazing area. In order to prevent creation of oxides on the workpiece surface to be joined, a gaseous flux is blown into the soldering or brazing area in a free atmospheric environment before and/or when the solder is fed to soldering or brazing area.
