Japanese Patent JP7256760

B2

A brazing method for brazing a material to be brazed without using a flux includes performing brazing in an inert gas atmosphere, in a state in which the material to be brazed is covered with a cover member (1) formed of an upper cover portion covering the whole upper portion of the material to be brazed and side cover portions covering at least some of the side portions of the material to be brazed, with the upper cover portion contacting the upper portion of the material to be brazed, and the material to be brazed and the cover member are held with a heat transmission promoting member (1) formed of an upper heat transmission promoting portion covering the whole or some of the upper cover portion of the cover member (1) and a lower heat transmission promoting portion covering the whole or some of a lower portion of the material to be brazed, with the upper heat transmission promoting portion contacting the upper cover portion of the cover member (1), and with the lower heat transmission promoting portion contacting the lower portion of the material to be brazed.The present structure provides a brazing method for performing brazing without using a flux, shortening time required for increasing a temperature of the material to be brazed with an inexpensive method, and achieving good brazability.
