Abstract
Provided is a method for bonding dissimilar metals to each other, the method comprising: dissimilar metal layer-forming steps (P2), (P3), (P4) for supplying, to form dissimilar metal layers; a second metal layer-forming step (P5) for supplying, on the surface of the dissimilar metal layers, a filler material formed of a second metal, and heating the filler material formed of the second metal to a temperature equal to or higher than a melting point of the second metal, to form a second metal layer formed of the second metal; and a second material-to-be-bonded welding step (P6) for welding a second material to be bonded that is formed of the second metal, onto the second metal layer.
Claims5
A method for bonding dissimilar metals to each other, the method comprising:
- providing a first material, including a first metal, to be bonded to a second material, including a second metal, the first and second metals being the dissimilar metals;
- a dissimilar metal layer forming step of supplying a mixed filler material, including a filler material formed of the first metal and particles formed of the second metal having a higher melting point than the first metal, to a surface of the first material, and heating the mixed filler material to a temperature equal to or higher than a melting point of the first metal and lower than a melting point of the second metal, to form a dissimilar metal layer;
- a second metal layer forming step of supplying a filler material formed of the second metal to a surface of the dissimilar metal layer, and heating the filler material formed of the second metal to a temperature equal to or higher than the melting point of the second metal, to form a second metal layer formed of the second metal;
- and
- a second material-to-be-bonded welding step of welding the second material to the second metal layer.
