<p>A first electromagnetic induction pump (46) composed of a plurality of electromagnetic induction pumps (46a, 46b) arranged in a widthwise direction of a work (P) is provided vertically along a longitudinal plate portion on a work carry-in side in a vessel (33). A second electromagnetic induction pump (47) composed of a plurality of electromagnetic induction pumps (47a, 47b) arranged in a widthwise direction of the work is provided vertically along a longitudinal plate portion on a work carry-out side in the vessel (33). A brazing fill metal is jetted upward by the electromagnetic induction pumps (46), to perform brazing of the work (P), which is carried in and out by jet waves of the fill metal. The plurality of electromagnetic induction pumps (46a, 46b or 47a, 47b) are arranged in the widthwise direction of the work to ensure jet waves having an adequate wave width and a uniform wave height in the widthwise direction of the work.</p> |
