    Patent number: 9162328
    Abstract: A brazing method includes fixing a padding plate on a base material such that the padding plate is arranged in a lower position from a groove formed in a repair region of the base material, and heating the base material such that a base material powder is melt, after a paste that base material 1 contains the base material powder which is formed from a same material as the base material is filled into the groove. The base material powder filled into groove can be prevented from flowing out from the groove even if being fused since the padding plate is arranged for the base material.
