ABSTRACT:
Disclosed therein is a filler metal (90) used as a bonding material in bonding technology by brazing and soldering and an apparatus for manufacturing the same. A flux cored alloy filler metal200according to a prior art has a problem in that a flux is leaked through a joint93during the brazing work or carriage of the filler metal. However, a sealed flux laminated alloy filler metal (100) according to the present invention is a laminated W-shaped filler metal (92) bent several times and having a compact W-shaped section and a flux (51) is filled between overlapped surfaces of the W-shaped filler metal (92), so that the powdered flux (51) is not leaked during the brazing work or carriage of the filler metal. Moreover, an apparatus for manufacturing the filler metal is automated to improve productivity.
