PURPOSE:To stably execute brazing of minute parts or repair of brazing by providing the function for adjusting brazing filler metal quantity utilizing a capillary phenomenon in the tip part of a soldering iron tip used for brazing. CONSTITUTION:A soldering iron tip 10 for brazing is constituted of a heating machine 11 provided to the vicinity of the tip and a soldering iron tip 12 having a metallic plating part. In the tip part of the soldering iron tip 12, one piece or plural pieces of thin grooves 13 are provided in the direction of the heating machine 11. By this groove 13, as for a brazing filler metal melted by the soldering iron tip 12, force for remaining by a capillary phenomenon is added to force for remaining in the soldering iron tip 12 by surface tension, therefore, it can be suppressed that the brazing filler metal flows out to a metallic tube to be joined from the soldering iron tip 12. |
