| Abstract: | The causing principle of the brazing defects was ascertained such as overflow, lack of bra zing, erosion, porosity and filler metal part melting, by analyzing the results of the experiment of 3A21 vacuum brazing. It is proposed a technology eliminating measure of aluminum vacuum brazing, and it is validated by the experiment of the vacuum brazing of test sample. |
