A first electromagnetic induction pump is disposed in a first reservoir, and a second electromagnetic induction pump is disposed in a second, independent, reservoir. Each reservoir is adapted to contain molten brazing filler metal. The electromagnetic induction pumps are effective to eject the brazing filler metal upward through wave forming portions into contact with an underside of a workpiece being conveyed along a workpiece conveyance path. The second reservoir is disposed downstream of the first reservoir in the direction of conveyance. At least one of the first and second reservoirs include a height adjusting device which permits adjusting the relative heights of the wave forming portions to adapt to the needs of the workpiece. The apparatus may be adapted to contain an intermediate space and an intermediate processing device between the reservoirs. In addition, a brazing apparatus having a pluralty of reservoir may have local nozzles fitted on the reservoirs effective to direct brazing filler metal to respective local areas of a workpiece. The apparatus having local nozzles may include an interference preventing space between the nozzles.
