PROBLEM TO BE SOLVED: To provide a brazing method for stainless steel components, a method capable of sufficiently securing joining strength of a weld zone even in the presence of an embrittled part in the fillet. SOLUTION: In a brazing method with which stainless steel components 1, 2 are brazed with each other using powder brazing filler metal 4, brazing is performed with Ni-P based or Ni-Cr-P-Si based powder brazing filler metal 4 in which Ni powder 3 is mixed, and then brazing is repeated using again Ni-P based or Ni-Cr-P-Si based powder brazing filler metal 4. In the initial brazing, joining strength of the weld zone can be secured. In the second brazing, a joint gap made in the initial brazing can be filled with the Ni-P based or Ni-Cr-P-Si based filler metal having a superior fluidity. COPYRIGHT: (C)2005,JPO&NCIPI |
